I wanted Lovie as well, but two points that make me think about this hire are an article from Don Banks about Andy Reid: http://sportsillustrated.cnn.com/nfl/news/20130104/andy-reid/index.html
History isn't on Lovie's side either. I still wanted him, but it's an interesting point.
The other point made was that a lot of 'hot' college coaches come from big time programs that get better players than their competition. Kelly, for example, get big time players and Oregon was no slouch before he got there. Marrone took crap and had some success.
