Ohio State needs to add a couple of things to this team, and it could/would completely change the context of how we view them.
1) This team needs to take better care of the ball, as well as create better opportunities off the bounce. Basically, they need better PG play. CJ and Keyshawn Woods have acted as PG1 and 2 most of the season, and turnovers have played a huge role in too many games. Substituting CJ/Keyshawn for Carton/Walker, to me, is going to be a huge improvement. Two true PGs who can beat their man off the dribble and force defensive rotations.
2) This team needs more shooting. More specifically, they need to make open shots. First off, the best shooters on the team are young guys who have been inconsistent. Adding a year of experience will do wonders for Ahrens, Washington, Muhammad, etc. But better yet, they just don't get that many truly open shots. Again, having true PGs who can penetrate and get the ball moving while the defense is scrambling means more chances to find open shooters.
3) This team needs more versatility and options in the post. If LeDee sticks around, he should develop into a better player. But, Liddell sounds like he should contribute right away and Gaffney's length could be a factor as well. Even if these guys aren't the best down low defensively, as long as they can put up a fight on the defensive side of the ball they should be able to take advantage of bigger, slower, less athletic bigs on the offensive end.
I don't think Ohio State is going to need to rely on the incoming players to be "super men" next season. They just need these guys to bring something different and change the game on the offensive end. More athletic bodies that can test opposing defenses will do wonders for the team next season.
