NFL teams selected 34 wide receivers in the 2009 draft.
The 49ers had reason to expect better from Crabtree, the 10th overall choice and second receiver taken in his draft class. Matt Williamson of Scouts Inc. hits on some of the keys for Crabtree heading into the receiver's third season. He sees vast potential for Crabtree in the red zone specifically.

The first chart shows 2010 production for the wide receivers NFL teams selected in the 2009 draft (minimum nine receptions). Note that the St. Louis Rams' Brandon Gibson entered the NFL with Philadelphia.
