I think Oregon fans have a different perspective on this than a lot of people. East Coast folks (I have been living on the east coast and mid west) just see Oregon winning a bunch of games under MC. Oregon fans see his upside of being a great recruiter and relating so well with his players, but we have also seen his down sides of not so exciting, unimaginative offense, mediocre game prep, and sometimes poor in game management.
Lanning is in some respects an unknown. He hasn't been a head coach. Oregon is a big stage for a new head coach, so there are questions. I had them myself, but he has come in and changed the culture before he's even moved in, hit homerun after homerun in hiring a staff and shown he speaks the right words, but also listens. So, I understand someone not rating this an A+ hire, but let's see what they are saying in two years. I think this will prove to be one of, if not the, best hire this year or over many years.
