1. Pryor develops -- Terrelle Pryor quieted concerns about his passing ability with a strong spring capped by an excellent performance in the well-attended spring game at Ohio Stadium. Pryor made significant improvement with his footwork and looked better on the high-percentage throws that dogged him at times last season. His first full offseason as a college player appears to have paid off, and Pryor looks primed for an All-Big Ten season.
2. Boom and Zoom -- Running back is the biggest void on the Buckeyes' depth chart, but Dan Herron ("Boom) and Brandon Saine ("Zoom") appear ready to carry the load. Herron built off his experience last fall as a backup and performed well this spring, while Saine finally appears healthy and ready to showcase the explosiveness that made him such a heralded recruit coming out of high school.
3. Big bad Boren -- Justin Boren will always be in the spotlight because he transferred from Michigan, but the left guard generated plenty of buzz with his play this spring. Boren brings brute strength and an edgy attitude to an offense line that needs a jolt after a subpar 2008 season. He has quickly become a favorite of Pryor's and his fellow linemen, and should bring a nasty attitude to the front five this fall.
1. Cornerback -- Chimdi Chekwa has a starting spot locked up, but the other position remains open entering the summer. Senior Andre Amos has a slight edge because of experience, but Devon Torrence, who played minor league baseball in the Astros organization the last two summers, made a strong push this spring. If Torrence focuses solely on football, the starting job could be his.
2. Kicking game -- It's no secret how important special teams has been to Jim Tressel's success at Ohio State, and the head coach is focused on replacing his starting specialists. Aaron Pettrey looks capable at kicker, but the punting job is a bit of a mystery with Jon Thoma and Ben Buchanan competing for the top spot.
3. Linebacker rotation -- Ohio State has plenty of exciting options at linebacker, namely Etienne Sabino and Brian Rolle, both of whom had very solid springs. The key will be finding the right combinations of 'backers and not being afraid to use younger players like Sabino ahead of veterans who played behind Laurinaitis and Freeman for years. It will be tough to replace the lost production, but Ohio State has enough depth, as long as players are used the right ways.
