My non-expert CFB take:
Sounds good:
Tony Reno - head coach at Yale
Joe Moorhead - head coach at Akron
Frank Reich - interim head coach at Stanford
Ryan Carty - head coach at Delaware
Maybe ok:
Jeff Monken - head coach at Army
K.C. Keeler - head coach at Temple
Ricky Rahne - head coach at Old Dominion
OMG NFW ever (smoke, fire, bad person, luggage)
Brian Kelly - unemployed, former LSU, Notre Dame, Cincinnati
Jon Gruden - Barstool Sports, former NFL head coach
Bobby Petrino - Arkansas interim HC
Chip Kelly - unemployed, former UCLA
ps on edit - there are probably folks in the 1st and 2nd groups that are mis-grouped, thus my "non-expert take"
