As far as fans are concerned, sure.
As far as the administration is concerned, no chance.
His team can lose this week, pummel Central Connecticut next week and will feel like they're back on track at 2-2 going into Virginia week—same way they thought the were hot **** after stealing one at Pitt and pounding bad Florida State and Louisville teams, before no-showing for FIU, Duke and Louisiana Tech.
This program's psyche under Diaz is the problem; all the buzzwords and key phrases after losses (and posting pictures of themselves on social media making a play in a game they lost).
The let the Alabama game roll off their back and showed up ill prepared for Appalachian State. If they beat Michigan State, they'll think all is good again—and if they lose, they'll have some bag of excuses as to why and will write some quotes about "hustle", "grit", "hard work" or "the process" on their social media, again with photos of one play they made in the game.

15-11 in two plus seasons under Manny—with no reason to think these guys are going to turn a corner anytime soon. (That doesn't mean they won't get a few wins this season—it means they're not going to buckle in and to play the kind of consistent football needed to truly compete for a division title.)
