If people understand the game and realize you need players like CMac to be a very good team - especially with a program like Iowa that isn't able to bring in a bunch of Top 50 players ready to contribute right away - then they would never have had problem with him seeing the floor.
He is an extremely valuable role player. He is tough mentally, has a high bball IQ, can guard 4 positions, is a really good passer and post-feeder, can handle the ball, and can rebound decently. If he hits open 3's, just makes him that much more valuable.
And it's not like he was ever logging starter minutes. He was 8th on the team in minutes last year. And he is a guy you definitely want in at the end of games with a lead.
