I was at the game yesterday as well. The two things I noticed were their defense out-scheming our offense (shocking, I know). There was one play, I believe it was when we were all the way on our own 1-yard line, a couple of their defensive players knew exactly what play we were about to run and quickly adjusted.
Another thing I noticed was Cam Newton leaving the sidelines after we had a pathetic three-and-out. I think he left then, because I didn't see him on the sidelines at all after that.
