I missed that but I'd be interested in taking a look.
I think there are a few reasons why people seem to think Iowa has a worse problem than other schools. (and maybe they do)
1) It's their team. I was talking to my wife's uncle yesterday, who is a Nebraska fan, and he had no idea of the Coker or McCall suspensions. Likewise, Iowa fans aren't paying attention to every player that gets dismissed from Florida.
2) Iowa isn't stocked full of 4 and 5 start blue chip recruits. Therefore, it hurts Iowa a lot more to lose one than it would say an Alabama or Texas.
Now these aren't excuses, and it's not all rainbows and unicorns for the University of Iowa football program at current, but the sky isn't falling either.
