Urban Meyer's Buckeyes are coming off of an undefeated season. Ohio State is also returning most of its offense, several of its stars and tons of potential on the defensive side.
Put those things together and the Buckeyes should have a successful season in 2013.
But after spring practice, there are still a handful of questions that could keep Meyer and his coaching staff up at night.
Surprisingly, the passing game won't be one of the things keeping offensive coordinator Tom Herman up at night, because Braxton Miller and the receivers have come a long way since last season.
However, there are still concerns facing the Buckeyes' coaches as they enter the summer months away from the team.
