The pick of TCU as a sleeper is just ridiculous. You can't be a sleeper if you are a perennial contender for the league crown. By definition, the sleeper pick has to come from outside of the top 3 of BYU, Utah and TCU.
I would say that both NM and Wyoming will be good teams this year but I don't know if they are true sleepers because 1) I don't think they actually have a chance at the title with BYU, Utah and TCU appearing very strong this year and 2) most people expect them to be good so again they are not really sleepers.
I honestly don't know if there will be any real surprised this year. AF and CSU should be really bad. UNLV should be bad but has some talent and might surprise. Suck Dog State lost quite a bit of talent but you have to think that eventually Coach Long will turn them around. I don't see them having enough talent to really surprise anyone but they may get to 6-6.
