Rak does seem to be unneeded this year, we have more talented forwards and he is kind of redundant to BMK at center.
But it is important to keep him happy. Rak is scheduled to be have a big role in the NC contending '14-'15 squad as one of the two main centers. Rak as a senior will be miles better than Chino as a first year. Let's keep that in mind.
If we look ahead for a moment to '14-'15, we should have our backcourt back with a year of experience, forwards Grant, McCollough, and Roberson along with centers DC2 and Rak. I don't think that squad will be underrated because everyone will be calling them title contenders.
So while starting Rak may technically "Boeheim" Roberson, it could be good for SU in the long term.
