The thoughts

Coach Kirk Ferentz on the Iowa linemen in this year’s class:

“They fit the profile we were looking for. We’ve had them in camps and had a chance to work with them which is a nice thing, a luxury for us to be able to coach guys. … We liked everything about their profiles and we think those guys have a really good chance to be good offensive players for us.’’

Coach Kirk Ferentz on Tristan Wirfs cutting down from 325 in football to 285 pounds for wrestling this season:

“I think he got recruited by his teammate and his coach or something. I thought it might take some sort of an amputation that was going to be impossible. It’s amazing that he’s lost that weight. For a guy to have that discipline, a big guy like that, that’s impressive.’’
