I root for BYU whenever they are playing anyone except Utah, other PAC12, Georgia Tech or Memphis. Leaves a lot of games where I’m cheering on my rival. Would I really want my rival to be a loser/patsy/cupcake team? How does that help the team I love? It raises the question of what animates a fan more - the success of their team, or the downfall of their rival? Maybe it is as simple as whether you’re a positive person or a negative person.
