At the end of the day, I don't see Dalton or Osweiler going into Foxborough and beating Brady, even with good defenses. The Peyton we've seen over the past year is probably even worse. Denver can get pressure, but with Edelman back in the playoffs as a safety valve, I just can't see it.
Roethlisberger maybe, but it's tough without Bell. And while their defensive scheme is good, the players themselves are just okay and the Patriots have a way of exposing things like that.
That said, I think I'd favor the NFC team in the Super Bowl.
