Carpenter was excellent at OSU. He was used primarily as a SLB and put his hand down on passing downs. Drafting him to play ILB was a mistake. Some guys just don't succeed in the league. ginn had very sure hands in college but forgot how to catch in through pros. For him it is as mental as anything, and I think the same is somewhat true for bobby.
As for manning up, OSU has leaned on 3 WR sets for the last decade, often using it as their main formation. Because of Duron's departure to a juco, they lack that third WR they usually lean on in the passing game (03 Holmes, 04-05 Gonzalez, 06 Robiskie, 07 Sanzenbacher, 08 Posey, 09 Duron).
As a result, they are leaning on Saine (power back with great speed), Stoneburner (4.4 WR in HS at 220 lbs), and FB Boren (blue collar guy with great hands) to fill that void. The first 2 are very difficult matchups, defenses have to choose whether to give up size or speed to cover them. The latter is more of a safety valve the defense loses track of.
