Don't give me this crap about how Iowa football doesn't discipline its players. Look back at that list of guys that got in trouble and tell me how many of them are still on the team. Only the ones that got into minor alcohol-related offenses were/are still on the team. And you can't say they take it easy on good players because Dominique Douglas, probably one of the best receivers Iowa has ever had, was immediately suspended and ultimately kicked off the team. And on top of that, Iowa suffered because of all these problems. They went 6-6 in 2007 and missed out on a bowl game. But guess what. Ferentz turned things around, instituted some discipline and Iowa won the 2010 Orange Bowl.
As far as Metcalf goes, the guy is your typical wrestler. It seems the more success they have, the more arrogant they get. There are a few exceptions, but wrestlers, stereotypically, are jerks. Ever talked to one of the Paulson twins? There's two of the biggest D-bags, you'll ever meet. Crying about it isn't going to change it.
