Eh, Riley Reiff did. So did Ford (twice). Reiff and Ford did about this time of year. If Iowa picks up 5 recruits this year, I'll agree that it has to do with the off-field problems. And I'm sure that those issues play a small role - but I'm guessing wins/losses play a much larger role, and Iowa has had more of the Ls than the Ws.
I disagree with this, Iowa's three BCS years came with recruits coming in from poor years record wise. The recruits coming in after the BCS years have done nothing but lose and end up in jail.
