I dont believe it would be an upset if the Panthers beat the Bucs. The Panthers defense hasn't allowed a touchdown in the last nine quarters, they are one of the top teams in the NFL.
I believe that the Cowboys game will be a shootout, but Warner is going to to need be quick in the pocket, because if he's not Ware and the rest of the Cowboys defense are going to get to him.
Should be a good day of football.
