You must be high. It's all about money. OU/TX is a HUGE Rivalry worth big money in visitors to the TX state fair, TV money Dallas vendors Norman and Austin Vendors. A aTm fan saying they are more important to TX is like an OSU fan saying that game is more important to OU than the TX game.
aTm is to TX what OSU is to OU. A little sister. That's it. They revolve their season around "if we could win just this one" regardless of what happens the rest of the season. Freud called this "penis envy" It's where little sister always envy's the brother for who he is and what she will never be. aTm will never be a TX and OSU will never be an OU.
You are so wrong its not even funny.
