Upsets can and do happen

I was looking at the games for week 1 and I saw some potential upsets. Of course you could ask 100 different people and get 100 different opinions. But still I'm sure all here would agree these are some games that could go to the underdog. We all have our favorite teams, but deep down inside we all like to see the little guy get one up on the big guy. Especially when noone thought they had a chance?
