Sounds like Will Muschamp
It does, doesn't it? I think Pruitt is a marginally better recruiter and DC, Muschamp is a marginally better HC.
The reality is, both should have stayed as college DC. They both could coach another 15-20 years, both would retire with another 5 or so NC rings. Instead, both will try to eek out careers at head coaching positions they aren't qualified for, both will likely have to dip back down into the DC ranks to 'rehabilitate' their careers, and eventually get fired and hang it up.
I dunno, it seems like going down as one of the better DCs in the history of the college game is a better legacy than retiring as a barely .500 head coach, but that's just me.
