Not sure what you were reading, but here's what he said regarding Clayborn against KO on passing plays...
"In this game he routinely beat Osemele when he knew a pass was coming. He got plenty of opportunity for that, as Iowa got off to a 3-score lead very early on. Clayborn beat Osemele over and over again in a variety of ways: inside moves, speed around the edge, bull rushing, or throwing him to the side: Clayborn did it all. And all that while routinely being double-teamed. This was about as good a game a defensive end can play without notching a sack. This game was a prime example of why relying on individual sack numbers to evaluate players is not a good idea."
If you think the guys on a Cyclone message board are better at evaluating talent, so be it.
