Front 7, the Buckeyes have no worries. Talent, depth and experience.
The DB competition, on the other hand, is going to be a battle from the Spring through the beginning of the season. Projected starters will be pushed and pushed hard by others. Here is my breakdown (barring injuries).
Starters: Corners - Ward and Sheffield; Safeties - Webb and Fuller. Nickel - Okudah
Back-up corners - Arnette, Davis, Williamson, and Wade. Arnette and Davis will play but I think Sheffield will beat out Arnette for the other starting CB spot with Okudah eventually locking down the Nickel. I believe Williamson will RS. Wade is the wild card, If he adds some good weight (15lbs or so) prior to the season, he could be in the picture. 6-1, 177 is a bit thin to be an every down player.
Back-up safeties - Smith, Norwood, Burns, Wint, Pryor, Riep. Smith could start over Fuller but I think Fuller is really going to show up this Spring and seize the job. Norwood, Burns, Wint, and Pryor will be in on ST while Riep is a RS. Keep any eye on Pryor here. He might add the size to move to LB and change the depth chart here.
As far as EGW goes, I was surprised he was moved to defense when he arrived. I think he will take advantage of this move and become a solid option at HB. OSU has McCall and Hill (more a true WR than an HB) as options to replace Samuel. Bringing EGW over gives the coaches depth and another option at HB. I think this move might pay off for the Buckeyes on offense.
