He was actually right about the defensive tackles until Jensen and Cousins got injured. Ayeni was injured from the start, so we'll never know how good the defensive tackles would have been had guys stayed healthy, but based on their play against K-State, Iowa, and Oklahoma State, I think it's safe to say they were indeed better until injuries took their toll.
Injuries are an excuse. It is still CPR's job to build the roster. He's been in Ames long enough that he's had plenty of time to provide capable back ups. I understand very well that ISU has been stricken by the injury bug the last two years, but that doesn't change the fact it's an excuse. Every team deals with injuries. Heck, I could argue Iowa could have played for a national championship had Ricky Stanzi not been hurt, but what good would that do me? It's an excuse. He did get hurt, and the rest is history.
