I think he plays enough for conditioning to be a factor, especially in BIG games against Illinois, UM, OSU and Purdue. We need his size against some very big fellas. He would probably even play more if he was in great condition.
Regarding the 3 candidates who will be playing the 5 position, @Suterman said this about the Oct 23 scrimmage vs Bradley:
Josh O. moved well and played fairly well. Did not play that much.
Rebraca was solid but not super productive.
Mulvey looked pretty good.
