I was on the side of giving Muschamp a pass for an improbably bad injury-plagued season but a coach can only lose so much before it becomes debatable that a healthy team even has a championship ceiling under said coach. Their 2012 season was pretty fluky insofar that they were as equally close to being in the national championship game as an 8-4 bowl game. This year the bounces all went against them and they're not even bowl eligible.
I struggle to think any Florida coach who loses to Miami, Georgia, and Florida State in the same season as leading their team to their first FCS loss is safe without a prior resume of success. Mark Richt earned a clanker season pass in 2010 by previously providing a decade of championship caliber teams. Gary Pinkel, too, earned one more year to show he could match wits in the SEC by building that program up over the last decade. Muschamp has been a successful coordinator but his equity as a head coach is roughly equivalent to Mike Shula's in 2006. Yeah, Shula had a 10-2 2005 season but he hadn't earned the pass for severe regression where Alabama wasn't competitive against anyone in the division much less conference.
