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.
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.
