There's only one great team. Kansas. Pittsburgh has too many injured. The Bills don't have playoff experience neither would they fare well against Kansas.
It's Kansas superbowl to lose. The only other team that maybe can put up a fight are the Packers. Tampa is still a mystery to me. But Kansas has the best quarterback, the best coaching staff remaining, best tight end, top 3 best receiver(debatable). They don't have the greatest defense but they're offense is just unstoppable.
To me it's their superbowl to lose.
