Not nearly as top heavy of a league. Mac/CPR/Chiz had Bob Stoops OU teams at their peak, Mac Brown Texas teams at their peak, Nebraska at the end of their peak, Art Briles Baylor at their peak, Mike Leach Texas Tech, Bill Snyder Kansas State.
Obviously not all of those were occurring at the same time, but most of them were better than the best opponents Matt Campbell faced (Patterson TCU, Lincoln Riley OU, Mike Gundy OkSt, Matt Rhule Baylor)
The benefit Mac had was playing an automatic win Baylor and not having to play UT and OU every year.
