PU needs impactful guards. Painter recruits wings ... not true guards. It's been his Achilles heel throughout his career. PU was one solid PG from being a legit NC contender this year. Obviously showed today.
No, he recruits guards. It's just that he doesn't recruit or "coach-up" some of his better guards that well and he doesn't conduct an offensive scheme that gives his better guards the space they need to be more effective offensively. He's had one future NBA guard in his tenure: E'Twaun Moore.
Also, when he recruits PG's, he recruits too many short ones (Korey Spates, Tarrance Crump, Lewis Jackson, Ronnie Johnson, Bryson Scott, P.J Thompson; Jackson at least had great athleticism and a pass-first mentality heading to Purdue). How many teams are successful in the NCAA Tournament with short PG's that aren't great shooters or scorers?
