Postseason struggles for Brady, Belichick

Greg M. Cooper/USA TODAY Sports

Tom Brady and Bill Belichick are one of the most successful quarterback-head coach duos in NFL history. But they have not had the same success in recent years.Next year will be the 10th season since the Patriots’ run of three Super Bowl wins in four seasons. Their last Super Bowl-winning campaign came in 2004.

What loss means for Tom Brady

Tom Brady Playoff Career

Tom Brady is .500 (8-8) in postseason games since New England's loss in the 2005 divisional playoffs at Denver. Before that game, Brady was a perfect 10-0, which included winning three Super Bowls.

In his postseason career, Tom Brady has a 2-4 record when facing a Manning as the opposing QB and a 16-4 record against all other starting quarterbacks.

But is it all on Brady? Consider that in Brady's first 10 playoff games (when the Patriots were 10-0), the defense allowed an average of 15.8 points per game and got a sack every 13.2 dropbacks.

In his past 16 playoff games, the defense has allowed an average of 22.9 points per game and got a sack every 18.2 dropbacks.

The Patriots have allowed 20 or more points in six straight playoff games.

But even with all of the negative trends, it's important to remember that Brady still owns the record for most postseason wins by a QB in NFL history. The next-closest active quarterback is Peyton Manning with 11.

Bill Belichick's successes and failures

Since New England’s Super Bowl loss to the Giants in Super Bowl XLII, the Patriots' playoff performance has fallen short of their lofty regular-season standard.

In the past six seasons, the Patriots have a .750 winning percentage in the regular season compared to a .444 winning percentage in the postseason.

Bill Belichick’s 19 postseason wins as a head coach are one shy of tying Tom Landry for most all time. He could have arrived there sooner, however; the Patriots have lost six of their past 10 postseason games.

Defense is what Belichick is known for, and the defense is what failed them against the Broncos on Sunday.

New England gave up 507 yards to the Broncos, the most they've allowed in a game -- regular season or postseason -- under Belichick.

The Patriots became one of six teams since the AFL-NFL merger to lose consecutive AFC Championship Games, and just the second in the past 25 years. The division rival Jets in 2009 and 2010 were the last to do so.

Of those six teams, only one -- the Raiders -- made the AFC Championship Game the next season. And that Raiders team went on to win not just the AFC Championship but the Super Bowl too.
