Houston was formidable in the late 70s, plus their 89/90 run with Ware and the first Klingler.
Rice always sucked, but had an AA RB Trevor Cobb in the early 90s.
Idk about TCU, but it was funny that in Athlon's 1994 Preseason Mag, instead of Wurffel, Manning, or a dozen other AA QBs they could have chosen, they went with TCU's Max Knake. The stats from 1993 weren't great, his team wasn't good.....just a rogue wave whiff by those folks.*
Baylor had an AA LB in the early 80s with big bug-eyes. Not much else.
But yeah, since the 60s, the conference was mostly fodder for Texas, Arkansas, and A&M alternating at the top. And don't forget the early 80s SMU teams! I wonder if the punishment was worth the crime.

*Knake was good in '94, but TCU went 7-5 and he benefitted from having a 1500 yard rusher.
