Right now, I say no.
Reasons?
Too many uncertainties on the offensive line.
Assuming that the defense will improve but can't be certain.
Bledsoe is still immobile quarterback who can be taken advantage of in the playoffs and in the big game.
But, if ...
the offensive line improves,
Julius Jones remains healthy
the defense improves, including a better pass rush
we find a free safety that allows Roy to play closer to the line
and if TO is TO
then I like our chances to win because we're built to win close games and TO is that X factor that Steve Smith or Mushin Muhammad were not when the Panthers played the Patriots in the Super Bowl.
If we had to play the Steelers, I don't like the Steelers' pass rush against the Cowboys offensive line. If we play the Pats, I like our chances better because the Pats defense isn't as strong as it once was, still Brady scares me.
If we have to play the Colts, we win going away as I believe Peyton can be rattled.
Still, I say we win one playoff game, maybe get to the NFC Championship game. We can go further if everything breaks right, but I'm not willing to say Super Bowl just yet.
