Brady rates as NFL's best QB in '09

Some might not be thrilled with Tom Brady winning the AP Comeback Player of the Year Award. A lot of players overcame adversity to have a great 2009. Vince Young, Cadillac Williams and Cedric Benson immediately come to mind.

The folks at Football Outsiders, however, could state Brady's case rather simply.

Not only was Brady impressive for rebounding from a reconstructed left knee, but Football Outsiders also determined he was the best quarterback in the entire NFL in 2009.

Before you spray your RC Cola onto the monitor, Bill Barnwell of Football Outsiders shows the math in a piece for ESPN Insider.

Brady finished ahead of (in order) Philip Rivers, Peyton Manning and Drew Brees in Defense-adjusted Yards Above Replacement. DYAR takes into account performance adjusted against the situation and opponent and is one of Football Outsiders' key statistical metrics.

Barnwell explains Manning and Brees didn't finish one-two because of schedule strength. Without opponent adjustments, Manning would've finished first, but Brady played much better defenses.

Barnwell's article ranks the best and worst five at every offensive skill position.

Also from the AFC East, Wes Welker ranked third and Randy Moss fifth in their receiver valuations.

Joey Haynos of the Miami Dolphins ranked third-worst among tight ends.
