I don't have a 2nd favorite but there are a couple teams I pull for.
The Colts (I like Peyton Manning and they have badass uniforms.)
The Lions (Because of Barry Sanders)
The Texans (I'm from Texas and hate the Cowboys)
... I was born in Phoenix but I hate the Cardinals, I wish they were in the AFC from the start. I would probaly pull for them. But as of now, they are my mortal enemy!
