They've won two national titles in 50 years. A&M hasn't won one in like 85 years. Mack Brown was there for 16 years and won the conference twice. Maybe it's more of a problem with Texas than the coaches.
I would take the top players in GA and FL over Texas anyday. Per capita, Texas is way down the list in NFL players. They are behind Hawaii, Delaware, and South Carolina. Georgia is #1 now, Tennessee is just a little behind Texas. Those Texas kids go to OU, OSU, Bama, and A&M in large numbers too.
