The Big 12 wasn’t actually killed but it was irreparably injured through selfishness and ugliness.
As a Texas fan I will admit DeLoss Dodds was the biggest a-hole in that or any room.
But schools like Nebraska, A&M and Missouri were culpable too. They all thought unequal revenue sharing was fair. Even in the months before they left, they all pushed hard for their greater share of the pie, only to later disingenuously cite unequal revenue sharing as a motivating factor in their decision to leave.
Most of the teams that stayed didn’t have a lot of other opportunities. David Boren is a big talker, but from my outsider’s perspective a million miles away, I credit OU’s AD Joe Castiglione as being a stabilizing force in a Big 12 entropy.
Now Texas seems to have a reasonably intelligent person at AD in Chris Del Conte. Hopefully things won’t ever get that bad again.
An alliance between the Big 12 and Pac-12 wouldn’t surprise me.
