The UCF and USF coaches are both guys to keep an eye on. Wake Forest's head coach as well, heck if Derek Mason takes the next step at Vandy, keep an eye on him. The market this year has some guys with promising futures, but with very little seasoning.
Scott Frost is a good one that I didn't think of; the turnaround at UCF has been nice. Another year, and perhaps he's on BK-at-UC footing.
Taggart at USF has already proven whatever he needs to prove; another year, even with improvement in winning the AAC, won't really show anything that you can't already see about his upside.
Derek Mason benefited from a weak SEC East, IMO, but either way, I don't think his potential upside justifies waiting another year with a lame-duck coach, just to see if Vandy stays competitive.
If Fleck stays, he's on the Herman trajectory of getting a chance to coach a huge bowl game this year, then gets to coach against USC and Michigan State next year in September. Performing well there would probably make ND forgot about all concerns regarding him.
There are a lot of coaches (Rhule, Mullen, Narduzzi, Taggert) who can probably make leaps in the eyes of the ND brass with a big year in 2017...also easy to put out feelers to guys like Stoops, Patteron, Petersen if they stumble and are out of the playoff picture early.
Those guys are who they are, though. They aren't going to make "leaps" that change their upside over the next year. You know what you're getting with Rhule, Mullen, Narduzzi and Taggart. You're getting young coaches that have turned around dumpster fires, or veteran coaches that have proven they can win with the right pieces in place. Those facts don't change, regardless of what their teams do in '17. It's not like they are limited-experience commodities.
And I'm not trying to debate you; just stating that if the ND admin needs to see another year from any of these guys, they're making a mistake. They will either miss out on an opportunity, or else they will get their guy next year and would have waited an extra year for nothing.
