Biggest reason for hope -- Terrelle Pryor's growth at quarterback
Pryor showed snippets of greatness at times last season, but he also quarterbacked an offense that finished 76th nationally in total yards (342.69 ypg) and 105th in passing (150.2 ypg). He was inconsistent on short and intermediate throws and took too many sacks. But, by all accounts, the sophomore made the necessary strides during the offseason and improved his footwork and throwing fundamentals. After being placed in a locker room that favored Todd Boeckman in 2008, Pryor knows this team belongs to him and he's prepared to lead Ohio State to another Big Ten title.
Biggest reason for concern -- Offensive line
Make no mistake: Ohio State has the personnel to make a major upgrade up front in 2009. But until the line proves it has moved beyond a very underwhelming performance last season, the jury's still out. There were some moving parts during the offseason, as Jim Cordle shifted to right tackle and Bryant Browning transitioned from right tackle to right guard. Justin Boren definitely provides a lift at left guard, and Mike Brewster is a budding star at center. But who will protect Pryor's blind side? Is Mike Adams ready? These questions must be answered by Sept. 5.
