Its absolutely creepy that a coach would want to sleep over in the recruits bedroom, the media isn't blowing it out of proportion, the facts are facts and its creepy and sad a coach would go to such lengths to persuade a teenage kid to attend the school he coaches at. As for due-diligence, quit trying to defend Harbaughs actions as it relates to due diligence. Jim had the entire spring, summer and fall to confirm if this kid was a good fit for his program, but he waited until two weeks before signing day to pull his offer without explanation. On the surface, its a terrible way to conduct business. There might be more details to help justify Harbaughs actions, but i doubt it.
p.s. I'm not a Pete Carroll, USC or Seattle Seahawk fan. I think Carroll was complicit in a lot of the illegal activities that took place at USC and he was looking to bend the rules as much as he possibly could without breaking them. He got out before the posse arrived and obviously has had great success in Seattle. Beyond that, I don't care much for him at all but think he is a heck of a coach and motivator, also understands the phrase 'plausible deniability' quite well.
