Indiana is losing several players to graduation (including Watford and Hulls) and entrance to the NBA draft (Zeller and Oladipo). Just today I saw on Inside the Hall that Maurice Creek will be graduating and not returning to play ball at Indiana. He will look for another school where he can complete his eligibility. Since he is going to grad school, he can start playing next season.
While this is quite an exit of talent from IU, it will also mean a very young roster. According to the article, only two of the scholarship players are upperclassmen. I know Indiana has some good talent staying and coming in. It will be interesting to see how their lack of experience will affect them.
