There are a lot of teams I dislike and I would also have a difficult time hiding it. I would also be a bad ref because I hate cocky behavior after plays and would throw a lot of flags for unsportsmanlike conduct.

Teams I dislike in no particular order: all the PAC 12 ( esp Stanford and Utah), BSU, New Mexico (mostly for hoops), Nebraska, Iowa, OK St, and any other team that BYU has lost to lately
