BYU in a number of ways. Many of their fans think BYU would lie, cheat and steal just to get a leg up on the aggies. Because apparently BYU has a well known history of lying, cheating and stealing?
Really it all boils down to they think BYU is thinks they're better than everyone, and that the BYU way of doing things is the right way.
And of course it all stems from the unavoidable reality that with a church school, some will get to go, and others won't. And who wouldn't think their church's school was better? Everyone would.
