Sure, we've all spent time gnashing our teeth at Texas for a myriad of offenses: nearly running the conference into the ground, their self-serving broadcast interests, etc. And while the Aggies have gone off to play in the bayou backwater, they'll always know a special place of disdain among Raider fans.
The more interesting question, the way I see it, is this: who do you loathe additionally, currently? Oklahoma State for the way we've matched up against them of late? Baylor for their improbable resurgence (and the fact that we seem to battle them for recruits)? TCU for the fact that some of their fans seem to think they'll waltz in the Jones after getting beat in their house last year? Someone else?
