The receiving core will be fine. Hartline, Robiskie, and Small are all very good. They will be the starters. Dukes is suppose to be dynamite, but for some reason gets zero PT. I'll have to look into why that is. I think he may have been in the coaches' dog house for something. Lyons was supposed to be the next Braylon Edwards coming out of high school. Course, in three years he's gotten zero PT, but OSU has also had tremendous players ahead of him. He'll be a junior. His time is now. The big thing about losing BOTH Ginn and Gonzo is depth. Beyond those 5 I just mentioned you're looking at true freshmen. if a couple starters go down the frosh will be in the two deep. If healthy though, no worries.
Pittman is the big blow. Mo Wells is transferring (I think Georgia Tech), so OSU is looking at Beanie, and two true frosh. That's it! Brandon Saine better be all he's cracked up to be.
The other player that was considering leaving early was Barton. OT is probably the thinnest position on the roster. Ohio State only has 4 OTs, and one of them (Rehring) is a starting guard. With out Barton, they'd be two injuries away from starting a TE or guard at tackle. Thank god Barton decided to come back!
