But if we win against Denver, we won't have to deal with Pittsburgh until the AFC championship, if at all.

As the 1st seed, New England would get to play the lower seed of the winners in the wild card round.

Pittsburgh being the 6th seed means we'd play whoever won the other game, or Denver if they beat Pitt (not likely).
