Fran's been highly rewarded for what he's done to date, with repeated extensions. Add in that the AD is incompetent, what's Fran's incentive for doing things differently?
If I kept getting raises and years added to my contract AND my boss gave every indication that the work I've done to date is just fine and to stay the course then why would I change things?
And this is in no way implying that Fran wants to keep falling short in the NCAA tourney. Of course he doesn't; just like almost every other coach out there he wants to win. I just think that he is in a position where he has no incentive to go outside of his comfort zone to try to do that.
