Stuck as a third receiver in New York, Manningham entered free agency hoping to land a big contract on the heels of an impressive performance in the Giants Super Bowl run from last season as well as his solid production as a backup in 2009 and 2010. When the big offers didnít come rolling in, he signed a modest contract with the 49ers expecting to start opposite Michael Crabtree but now appears likely to enter the season as a backup, sharing the deep threat role he fulfilled with the Giants with Randy Moss in San Francisco. Itís one thing to be the third receiver in a pass-happy Giants offense that lacks a solid receiving option at tight end but quit another to produce in that same role in a conservative 49ers offense that has Vernon Davis. Manningham has never been a great on short and intermediate routes so he figures to see a decline in his production in 2012 (keeping in mind that he struggled with injuries last season). He might not be worth owning in standard 12-team, 16-player leagues in 2012.
