Guards dominate in RL college. Because bigs are scarce, most bigs sign at a level higher than their skill warrants. Guys that should be in D2 are playing in low D1. Guys that should be at the lowest level of D1 are at Creighton, etc. Fans watch a game, see a stellar center and exclaim, "Why don't we have one of those guys?" Answer: there are only a handful of "those guys."
