Iowa also got 9 blocks out of White, Woodbury, Olaseni and Basabe...not to say that is going to happen every game, but having Adam/Gabe at the Center spot and having size make a difference. I don't think if Eric May plays every game he will lead Iowa in blocks this season.
The impact of Woodbury/Olaseni is not going to be felt on the offensive end because they don't have to be big scorers, oppotunity scorers, yes...you will see it in the Rebounding and Blocked shot numbers, not to mention overall defensive stats.
Brunner wasn't the biggest guy in the world, but he played alongside Hansen, that made a huge difference in what Brunner could do, if Brunner was playing the 5-spot during his career, I doubt we would think he was nothing more than an average player that "tried hard." McCabe/Basabe will have better numbers than they did last year when all is said and done becuase Woodbury/Olaseni will be occupying space and will not be ignored.
