Projecting Player Performance
7/6/07
The “Gut Feeling” is often synonymous with a sense
of desperation resulting from a lack of preparation. The Gut Check
is a huge proponent of studying the numbers, but there’s
a point where one can place too much emphasis on the wrong information.
This can result in the undervaluing or overlooking a player’s
potential. Therefore, The Weekly Gut Check is devoted to examining
the frame of reference behind certain number-driven guidelines
that fantasy football owners use to make decisions.
Although The Weekly Gut Check doesn’t claim to be psychic,
he does believe that he can dispel certain numbers biases and
help you make the best choices for your team. We’ll keep
a running tally of The Weekly Gut Check’s insights. This
way you can gauge his views as something to seriously consider,
or at least seriously consider running the opposite way as fast
as you can!
Many fantasy football draft strategies involve owners projecting
the statistical performance of players. Although the Gut Check has
veered away from projecting stats for every offensive skill player
with a likelihood of contributing on a roster, there are still a
large percentage of people that either project their own stats,
or at least consult the projected stats of others. The Gut Check
uses FF Today’s Cheatsheet
Compiler and Draft Buddy as a stats projections resource. These
are reasonable figures and they are calculated with a basic historical
understanding of NFL stats, which shouldn’t be understated.
But how does one do projections? There are several ways. This
article will serve as an introduction to some basic techniques.
The next four articles will cover the statistical high points
of the offensive positions since the advent of the 16-game season
in 1978. This data will help the reader determine whether his
projections (whether his creation or from another source) have
a historical basis in reality.
Step One—Determine The Amount of
Players To Project
One should figure out how many players he or she wants to project.
Despite the fact this is a hobby, projections require work. The
Gut Check recommends you work efficiently. In fact, he suggests
you forget the idea of projecting performance, save yourself potentially
hours of work, and buy the Cheatsheet
Compiler and Draft Buddy. This application will provide you
carefully weighed projections and all you have to do is enter
your league rules. Plus you can view a variety of projections
or import them from other sources. Even if you insist upon doing
all your projections, the Compiler is a great
format to maintain an organized list that you can transfer
to the Draft Buddy when you’re ready to select your team.
If you’re absolutely against the idea of spending money
on this product—despite the fact that even if you valued
your time at minimum wage, 99% of you would spend a lot more money
doing this work yourself than simply buying Mike MacGregor’s
terrific product. Plus you support one of the last remaining free
fantasy football information sites on the Internet. Other options
include using Crank Scores
or learning more about the Average
Value Theory.
But if you are dead set on doing projections on your own without
the help of these resources, yours truly is here to help (though
he’d also recommend Projection Pal as a way to organize
your results and make it easy to update as player values change
throughout the preseason). Once again you should factor how much
time you have to project performance. Your resources should be
based on your available time. Yours truly would budget at least
2-4 hours per position (kickers and defenses possibly excluded)
depending on whether you only intend to project starters or all
players on the depth chart of a team. After these initial projections,
one may need to devote an hour a week to update the results when
players get hurt or their standing with the team changes. This
depends on how far from your draft date you decide to project
performance. Below, the Gut Check will recommend the resources
that will best suit fantasy owners according to their time allotment
and the amount of players I decide to project.
Step Two—Resources
Limited Preparation Time (4 hours
or less): If you just don’t have enough time, get
the Compiler and use the projections there as your base set. Make
adjustments where necessary or import projections to the application
from your on-line source of choice. Another option is to copy
and paste online projections to a spreadsheet and you can make
any desired adjustments. The Gut Check strongly recommends you
take projections that include statistics for attempts, yardage,
and touchdowns along with projected fantasy points. Otherwise,
you cannot make logical adjustments. If you’re really hard
up and lack the cash to buy the Compiler, use these
projections or Mike Krueger’s rankings
format, which is what the Gut Check would do if he were in such
a situation. If your normal mode of operation is to buy a magazine
and use those outdated rankings—which if you’re reading
this article, yours truly finds very doubtful, you might as well
spend the extra ten bucks and get the Compiler and Draft Buddy
otherwise you simply just aren’t thinking straight.
Minimal Preparation Time (4-16 hours):
Get the Compiler to make
the most of your time and download several projections that you
like. How do you know which projections are good ones? Check out
the remainder of this series over the next four weeks—if
you have that much time prior to your draft—and compare
the information with the projections you review. This will help
you spot the well-conceived figures from the rest. Even with the
lists you like, begin to take note of the players with numbers
that you disagree with and those will be the players of focus.
With limited time, it doesn’t make sense to try to project
any more than 10%-25% of the total players on your list. This
is because a good draft list of players will have at least 64
QBs, 96 RBs, 128 WRs, and 64 TEs—when one includes the kickers
and team defenses one will have 416 players due to the necessity
of keeping depth chart players in mind. At least all the starting
QBs, two-thirds of the RBs, three-quarter of the WRs, and two-thirds
of the TEs should have projections. Considering it will take the
average person 10 minutes to do a good job projecting a player’s
performance—some players will take longer than others—one
is looking at a minimum of 40 hours of work to project every player
the Gut Check would reasonably recommend. If you want to do a
decent job doing your own projections but only have 4-16 hours,
then forecasting 10%-25% of the players you should have on your
list will fall within your time requirements. As an alternative,
the Gut Check would strongly recommend you consider using the
Average Value Theory or the Gut
Check’s Crank Scores
as a basis for compiling a list without projecting performance.
Of course, yours truly recommends you incorporate Crank Scores
even if you do projections—rating player consistency is
a good way to tier players with similar values.
Moderate Preparation Time (20-40 hours):
You should be able to forecast 50%-100% of a solid list of players
with this amount of time. Obviously, the Compiler becomes a great
tool for inputting your
own projections and allowing the macros to do the work of
tallying the fantasy points for your league scoring system. Yours
truly knows this may seem like shameless promotion of an FF Today
product, but it’s the best product of its kind on the market—and
the Gut Check has tried several products that followed in its
footsteps (Mike’s was the first of its kind). So whether
it’s the Compiler or your own spreadsheet where you input
your initial projections, the next step is to take a look at last
year’s stats—use
FFToday’s stats so you can look at both the first and
second half of previous seasons—to see if a few theories
apply to some of your players. If so, these concepts may impact
your projections. Here are some concepts one should consider for
step three of this article:
Once you’ve projected performance, acquire some average
draft position (ADP) data to note whether your projections may
be over valuing or undervaluing the player in comparison to your
peers. When the Gut Check says this he doesn’t mean you
are wrong, only that your views differ from the norm. Having awareness
of your differences from the rest of the crowd will help you make
wiser selections on draft day.
Emulating The Reclusive Lifestyle
of Howard Hughes: This must mean you intend to forecast
the performance of every player on an extensive list and will
be committing the time to create a unique list you will feel strongly
about your data. The Compiler, ADP data, the articles mentioned
above, and Crank Scores to create separations among players one
may have within a similar tier of fantasy points. In essence,
you’ll do everything listed under Moderate Prep Time, but
more extensively.
Step Three—Begin With A Simple, Clear
Cut Method As A First Draft
Once you have your list of players to forecast it is time to make
sure you’re using the right kind of stats to create a solid
performance projection. Everything should be cause-and-effect
in nature when projecting numbers. These are the key stats one
should project for each position:
QBs—Attempts; completion
percentage; passing yards; passing tds; rushing attempts; rushing
yardage; and rushing tds.
RBs—Attempts; yards per
carry; rushing yards; rushing tds; receiving targets; receptions;
yards per catch; receiving yards; and receiving tds.
WRs and TEs—Receiving
targets; receptions; yards per catch; receiving yards; and receiving
tds.
Stats such as yards per carry, completion percentage, and yards
per catch will help keep your expectations in check when coupling
them with attempts or receptions. Another stat the Gut Check didn’t
mention for quarterbacks, but is also very helpful, is viewing
the yards per completion for each quarterback. This will help
you see the differences in the passing game of the offense each
quarterback uses. An owner will be able to see clear differences
between west coast offenses and vertical passing attacks—important
differences to create realistic projections.
An owner should begin with attempts (for RBs and QBs) and targets
(WRs and TEs). He should take a look at 1-2 years of stats for
the player in question. Let’s use Edgerrin
James as an example player to forecast performance. We’ll
start with two years of stats.

The Cardinals RB had nearly the same attempts, targets, and receptions,
but his yardage and scoring totals were dramatically different.
This is why yards per carry/reception is so important and it is
the tell tale difference between the efficiency of the Colts offense
and the inexperience of the Cardinals unit. James’ 330+ carries
with just a half a yard difference generates nearly 450 more yards
on the ground—the same can be said about his receiving production.
These differences can be attributed to the quality of quarterback
and offensive line play, if not the fact that James had 384 f-carries
in 2005—14 more than the dreaded 370-mark that is a high predictor
for decreased production the following year for RBs. These three
factors should help you have a good basis for projecting James’
numbers.
One of the Gut Check’s favorite runners of this era, James
missed the 370-mark for f-carries in 2006 and will be playing
behind a line that might have an upgrade with first round pick,
Levi Brown. He’ll also have Matt Leinart with a complete
year under his belt. The Gut Check believes James should improve
upon his stats in what will likely be the swan song of his most
productive years as a runner as he nears his athletic prime at
29 years of age.
One could be extremely methodical and calculate the average difference
in yards per carry for a starting back between the year he had
a rookie QB under center and that QB’s second season, but
the Gut Check isn’t going to do this just for an example.
Let’s just say James will improve his yards per carry from
3.44 in 2006 to 3.9 in 2007, a bit closer to his 2005 average
and a good half-yard lower than his second half average with Arizona.
To yours truly, this is a conservative estimate considering how
James looked from weeks 10-17. Conversely, he’ll lower the
yards per catch average to 5 yards because as James’ ground
production improved, his yards per catch dipped closer to the
average of his Indy days.
Now let’s focus on attempts, targets, and receptions. First,
one should ask whether there is any reason—barring injury—why
James won’t receive similar attempts this year. Yours truly
doesn’t think so. If anything, coach Whisenhunt will likely
place more emphasis on the run. This should mean James gets at
least as many carries. The difference will be the increased efficiency
of the running game. Forecasting James at 340 carries seems reasonable.
At 3.9 yards per attempt, James would then gain 1326 yards—still
starter-worthy ground stats. It would seem James has fewer receptions
in this offense, but not significantly less. During the second
half of 2006, James averaged nearly half the targets and receptions
as the first. Let’s say James will perform closer to the
second half of his 2006 stats as a receiver. This means he’ll
average 2 receptions per game for a total of 32 and 5 yards per
catch his receiving yardage will be projected at 160 yards—nearly
the lowest of his career.
But this doesn’t make sense for one of the better receiving
backs in football. Additionally, Matt
Leinart will likely be smarter about checking down to his
back with another year under his belt. Look for James to have
the number of targets and receptions closer to his 2006 amount
when Kurt Warner was under center. Look for 3 catches per game
for a total of 48 and forecast a slight increase in yards per
catch at 6.25. This will put James at 300 yards receiving.
Touchdowns are trickier to forecast. One method is to calculate
touchdowns per game. For James it would mean .375 scores per game
on the ground and .0625 scores per game through the air. But the
Gut Check believes the rate of touchdowns should be predicated
off attempts and not games. Therefore, James ground scoring rate
last year was 1 score every 56 attempts and through the air, 1
score every 38 catches. In 2005, James had a much higher rate
on the ground with one score every 27 carries. The Gut Check once
again looks to James’ rate of scores in the second half
of 2006, when the Cardinals running game seemed to improve. The
rate of scores per carries was 1 for every 50—not much better.
Still, touchdowns come from defenses that are off balance due
to efficient offensive play. Leinart’s improvement should
increase the overall offensive efficiency, but how does one link
Leinart’s ascent to James’ scoring production?
One method is to look at Whisenhunt’s last team’s--the
Steelers--ratio of rushing and passing scores between the starting
QB and starting RB in 2006. Roethlisberger had 18 scores to Parker’s
13 in 2006 and Big Ben’s 17 to Bettis’ 9 in 2005.
The 2006 ratio is 1.38 QB scores for every RB score. For the sake
of simplicity, let’s use this ratio and apply it to Mike
Krueger’s current projections for Matt Leinart’s 18
passing tds—which will give James 13 scores. The same could
be done for James’ receiving scores, which would give him
3 receiving tds.
For those of you keeping score, the Gut Check’s preliminary
projections for James would be:

Yours truly has a bit more optimistic forecast for James as a
scorer. Will the Gut Check lower his expectations for James in
this area? Let’s go to the final step.
Step Four—Refining Projections
This step is where you need to consider factors such as injuries,
players on the depth chart competing for time (highly regarded
rookies), and recent historical performance of the player in question
and his current offensive system. In the case of Edgerrin James,
his surrounding personnel remain nearly the same with the exception
of Levi Brown and a new coach. There are several cases of rookie
linemen jump-starting the ground game with their performance,
but it is no guarantee that Brown will follow suit. But the addition
of a coach who has success with emphasizing the run and played
in offenses steeped in a ground attack—Joe Gibbs Redskins
of the 80’s and Dan Henning’s run-oriented offense
with the Falcons—the Cardinals offense should be more efficient.
James should have a stranglehold on the starting job. J.J. Arrington
enters his third season and has done nothing to indicate he will
earn more playing time. Marcel Shipp is a consummate backup.
So in this case, the Gut Check would only look to adjust James
touchdowns. Although the Steelers ratio could be applied to the
Cardinals, Pittsburgh’s defense keeps the offense in games
and provides them time to run the football. The Cardinals defense
is a group with talent but they aren’t as effective—they
allowed nearly 30 yards more per game on the ground and nearly
20 more yards in the air than the Steelers. As a result Arizona
allowed opposing offenses more time of possession than Pittsburgh’s
and this was one cause for the Cardinals offense to throw more
with limited time. In addition, Pittsburgh lacks to great redzone
threats on the outside like the dynamic duo of Fitzgerald and
Boldin. This in itself should detract from the Gut Check’s
forecast of James’ touchdown potential. Knocking 4 scores
off Edge’s totals (3 rushing and 1 receiving) seems pretty
reasonable.
As a result, James would likely have somewhere between 234-258
fantasy points in a traditional scoring league (non-ppr), depending
whether you refine Edge’s projections as mentioned above.
This would place James somewhere between 4th and 8th overall at
his position in a set of projections for 2007. The Gut Check doesn’t
find this too surprising, because James was the 3rd-most consistent
back in fantasy football in 2005 and Willie Parker, Whisenhunt’s
starter in Pittsburgh, was the 4th-most consistent back in 2006.
James returning to a higher level of consistency would be a good
bet. Still James’ ADP will likely make him a bit of a draft
day value since it is likely his projected stats are higher than
the public perception of many that don’t do forecasts. The
implications could mean you can snag him as a possibly a #2 RB
for your fantasy squad. If you trust the methodology of your projections,
this will be a bargain. And that’s why good projections
can make or break your fantasy season.
