He was saying the same things on the radio yesterday as well. Very, very critical of Clayborn. When Iowa is bad, he blasts them with no mercy. In 2007 he called them "mutts" after the Iowa/Minnesota game. When Iowa is good, he is very complementary to Ferentz but has always doubted Iowa's talent.
From an outsider's perspective I can understand. Clayborn, Ballard, and the rest of Iowa's DL was expected to dominate and they did anything but. Particularly in that Minnesota game in which Clayborn was handled very easily. Star players are very easy targets when things don't go well.
In general this guy is just a very negative columnist. Glen Mason was his favorite target. It makes sense for the Star Trib because Sid Hartman is such a homer they need a negative guy to balance things out. They have a local TV show up here on Sunday nights and their conversations are pretty funny.
