"Build it from scratch"..... the way he did at Florida, or Ohio State? He's never inherited a 1-15 team before. And he's never coached in the NFL. He's succeeded in college in large part because he out-recruited his rivals and stepped into very established programs. Remember Nick Saban?
Urban Meyer is not used to going 9-7 and calling it a great year.
I would prefer someone with a stable personality, no history of medical issues causing him to quit, a track record of winning and if possible, developing QB's in the NFL. But I'm not making the decision.
You are remembering wrong.. (don't mean to sound rude)
The Gators post Spurrier hired Ron Zook who led them to the following records:
8 - 5 (Lost Outback Bowl)
8 - 5 (Lost Outback Bowl)
7 - 4 (Fired) (Team lost Peach Bowl)
This counts as rebuilding a program especially considering the standard that Spurrier set.
OSU:
Took over from the debacle of sanctions that Tressel left and the 6 - 7 record of Luke Fickle in 2011. Again this was rebuilding a program.
At both of his stops at Major Power 5 programs he was taking over troubled/down programs and had to build them back up.
Even at Utah he took over for a program that went 5 - 6 the year before.
So yes comparatively coming into the situations at Florida and OSU could well be similar to coming into an NFL team that has struggled.
This doesn't mean that personally I think this is the right fit, but to dismiss his ability to build/rebuild a team ""from scratch" (honestly that was a poor choice of words) is a bit disingenuous.
