Those are the offensive scores in their nine playoff losses since 2001. Seven times they scored in the teens. The Jets loss was the softest 21 you can imagine. Same with the 2013 Denver loss where the Patriots were losing 23-3 before garbage time. The offense has routinely faltered since they became a high flying passing attack. But they did bail out the defense in 2014 with a ridiculous 36 PPG and FIFTEEN offensive touchdowns.
However, the defense played very poorly in those losses as well. The only games I give them a pass for are Denver in 2005 and 2015. It's especially bad when you look at the opposing QB in most of those games. Mark Sanchez, Joe Flacco, Eli Manning?
Basically, for the most part, there is plenty of blame to go around for the offense AND defense in these losses.
