If the Patriots can find a great pass rusher, then I say Packers vs Patriots.
Right now, I can't see anyone but Packers vs Steelers.
I think we're the most talented team in the league, as I thought last year.
And as for the Steelers, I don't see any team with the QB + defense they have. If the Colts, the Patriots or the Chargers can somehow field a very good defense, or if the teams that have a very good defense (Ravens and Jets) are able to improve their QBs to the point where they win games, rather than manage the offense and not cost them games, then maybe them.
But, nowadays, if you don't have a QB that can win you games, and you don't have a D that can do the same the times the QB is unable to, you don't win the SB.
The Packers have it. The Steelers have it. I think the Saints have it. I don't see anyone else, right now...
