The Packers flaw is that their record when leading at halftime this year was 8-5. 5 times their defense blew 4th quarter leads. That's an awful lot. I just think somewhere down the road this stat will come back to bite them. I think its in Chicago, but I wouldn't be shocked to see Ben lead the Steelers to a 4th quarter win on the Packer defense, either.
Except this wasn't the case -- they've only had four 4th quarter leads that they've lost. Also, any of these "leads" at half time that they lost, the leads were never bigger than a touchdown. Moreover, their defense seems hardly at fault:
In CHI, Jones fumbled the ball on GB's 46 setting up the winning kick.
In WAS, Rogers threw a pick that set up the winning kick.
In DET, GB had a 3 point lead, in a game that finished 7-3.
In NE, their lead was 3 points and they were playing with their
backup QB.
This idea that GB's defense hasn't played well this year, or somehow collapses under pressure, is a figment of one's imagination.
