I think many people have inflated opinions of the "traditional programs" that have left.
Lets clear this up. Records show that A&M sucks at football. They stink. They suck. They have never accomplished anything. They are terds. Big, fat, overrated terds with male cheerleaders.
As for basketball, they have been pretty good (not great, but pretty good) for a couple of years now. Prior to Gillispie, they sucked. They were worthless. They, along with Baylor, were automatic wins. They went 0-16. They are freakin worthless.
Now, Nebraska. I love Nebraska, but they left because they couldnt win the Big 12. They couldnt field an elite team. When the option died, Nebraska took a huge shot in the chin and they still havent recovered.
As for basketball, their a joke. I loved them because they fought hard and were always the underdog, but they suck. They havent been to the NCAA Tournament more than once, I dont think. They are worthless. Only fun to watch them pull upsets here and there and play hard. I think they have a great coach, but they are nothing.
Colorado... my goodness, Colorado. Talk about a totally worthless program. I lived in Colorado for 6 years, in Denver. I went to college there. Nobody cares about them. Their facilities are trash. No local recruiting potential. They have sucked in football and basketball for a long freakin time. They got lucky and got Cory Higgins and Alec Burks under the radar, and they still didnt make the tournament.
TCU has been fantastic in football since 2005. Undefeated season, BCS game winner, coach of the year, huge program expansion, top 15 rankings, no losing seasons, etc.
This is an upgrade people. The Big 12 is going to shed some fat and move forward, and these schools will fade off into obscurity. As if they arent already there.
