Yes, as of the current roster, getting a couple of decent bigs is the first priority. However, I think Brown, Stokes, Wade, and Sneed make a good foundation for anyone.
We'll see about Love and Diarra, who I think could both be pretty decent players.
I still think the roster will be in pretty good shape if a change is made. FWIW, I still don't think a change is likely. We likely will win most of our home games (even KU) and steal one more on the road because oscar will oscar.
