Urban Meyer being #1 - He's not coaching right now so if I was the AD I would not be doing my due diligence if I didn't at least ask. His record should require no further explanation.
Hugh Freeze being #2 - He has turned every program around he's coached both before and after Ole Miss. This is a highly experienced yet young head coach proven to win. He can recruit anywhere in the south. He has a 70+ win%.
Luke Fickell being #3 - Has a 70+ win% has turned Cincy around and has done it there 6 years. Less proven than Meyer or Freeze is why I would slot him #3.
If I were AD I would chose coaches by track record of win%. I would seek out coaches who suck then succeed then suck, or succeed then plateau last. I'm not looking for a Cinderella hope and pray it fits even though dude was blah or sucked and maybe i hope that the name "Nebraska" magically makes them better. I'm paying a proven winner to win football games not to win moral victories.
Winners win, it's not complicated.
