That... doesn't matter.
Baylor was an afterthought before Briles. Kansas was an afterthought before Mangino. Clemson was an afterthought before Dabo. What was Ole Miss before Freeze? Who cared about TCU or Boise before Patterson and Petersen respectively got them to the top of the mountain?
It's so weird that people are so concerned about this when we're still currently packing out 90k for a team that's won 16 games in five years, and had 2 out of 3 losing seasons right before that. So what if the right coach has to build for four years and people's attention wanes further? If the coach is good, thf the coach is good, they'll develop a good team, and then the attention and interest will come right back.
