In any number of ways, this past decade could rightfully be called the decade of the passer.
In 2009, this is especially true. Now, passing success has always been a large indicator of a team's success, but it seems that having an elite quarterback is the hallmark of every playoff team still alive.
It seems a given that having an elite player at such a key position would be a fast track to the playoffs, but you could argue that the league's best running back, cornerback, inside linebacker, defensive tackle, wide receiver and left tackle are all sitting home right now.
(For posterity's sake that list would be Chris Johnson, Nnamdi Asomugha, Patrick Willis, Albert Haynesworth, Andre Johnson and Joe Thomas, in my humblest opinion, though Darrelle Revis is just as good as Asomugha. We'll debate this later, I'm sure.)
Contrast that with the fact that the only elite quarterbacks not in the playoffs are Matt Schaub and Ben Roethlisberger, and it's obvious: the NFL is a quarterback-driven league.
With that, let's rank the 2009 playoff quarterbacks from worst to first, based on their current level of play and what we can expect to see from them in the playoffs.
