He didn't say offense. He said he carried the entire team. That defense was outstanding. Rated 6th in points and yards and had play makers everywhere. They played great in the SB forcing a pick, fumble and sacked Manning five times but Newton's pick and two fumbles cost them the game.
If you want to say any one person cost Carolina the Super Bowl it was RT Mike Remmers, and by extension OC Mike Shula who left Remmers on an island 1v1 with Von Miller the entire game.
No quarterback would have stood a chance with the game's premier pass rusher having free shots to strip sack him over and over. I said leading up to that game that the only way Denver stood a chance is if Von Miller goes off, and that's exactly what happened.
The multiple drops by Carolina WRs throughout the game didn't help either. That's what happens when you have a bunch of JAGs as your WR corp.
