Johnsonís hamstring injury in Week 4 torpedoed the hopes of many fantasy owners as one of fantasyís top rated wide receivers went on to finish the year with the lowest level of production of his career. By seasonís end, Johnson had appeared in just seven games, amassing 33 receptions for 492 yards and two touchdowns, averaging 11.2 fantasy points per game, the third worst performance of his nine-year career. Johnson will be 31 years old when the season starts and with 12 missed games over the past two seasons, there are legitimate concerns as to whether he can remain healthy for an entire year. Adding to those concerns is the arthroscopic surgery on his knee that he underwent in May. While his health is up for debate, Johnsonís talent remains top-notch and he will eat up plenty of targets in Houstonís passing attacked with no clear-cut starter opposite him and Owen Daniels seemingly in decline. Offsetting those positives is the fact the Texans are clearly a run first team. AJ is worthy of being drafted as a mid to lower tier WR1 in 2012 but the risk of grabbing him has never been higher.
