If we find a way to get to the playoffs, then beat the Raiders, Steelers and Patriots (best QBs in AFC for the D to prove itself), then beat whoever the NFC has to offer, GB, DAL, or SEA (best D in NFC for Luck to prove himself)... anything is possible.
I'm optimistic. We did it in '06. We just need to get to the playoffs, then play our best football.
I'm just being realistic. We might not even make the playoffs this year, especially if the injury bug strikes. And if we do get to the playoffs, I'm sure the road will go through Pittsburgh or NE.
