Honestly, I think Fran has a little bit of the GMac syndrome. He still recruits and coaches like he is a mid-major coach. This year he looked like he was close to getting a major player in Tyler Ulis, yet lost him to Kentucky about a week after he made his official visit to Iowa.
Like GMac, Fran has talent on the floor, but I don't think he gets the most out of his players all the time. Frankly, I would not start the same team that he does, but I can see why he does it. It allows him to have at least 3 good players on the floor at all times, with a couple of marginal players. I think the problem with doing that is that there is just too much time that you do not have your best team on the floor. Yeah, you go 10 deep, but if those are not 10 quality guys, then what does it gain you? If your starters can not play for 32-35 minutes per game, then you have a conditioning problem, or they have been trained wrong.
I think Iowa runs a very structured offense and defense, which works for them. Fred allows much more freedom for his players to play their game. Fred's offense is space things out, move the ball, create as many mismatches as possible, find the open man and shoot when you are open. The set plays for him come out of the time-outs, or when the ball is taken out-of-bounds.
