That's not the right way to look at it. First off at his height at VCU Shaka would not come to SJU. He was looked at by much bigger jobs before jumping to Texas.They made the tourney in their first 5 seasons in the A10 with Shaka and Wade and only 2/5 with Rhoades so far, and they aren't in the at large picture at this point for this season either.
Secondly the last 5 seasons Rhoades has finished 1st, 8th, 2nd, 2nd and currently 1st in A10.
Like I said not the sexiest choice but consistently good in A10.
