I completely agree with the idea that when Mike McCarthy has a big lead, especially late in the game, Mike McCarthy gets into a conservative run out the clock mode (where he continues to runs it on first and second down), which gives the other teams chances to get back in the game.
But Jennings seems to be specifically talking about the 2011 season, and I think he's 100% correct with the 2011 regular season... that the Packers would get a huge lead... and then get conservative on offense, which led to more punts, which left the defense on the field a LOOONG time, and give the other team a chance to come back...
that being said... the Packers went 15-1 in the 2011 season. So Jennings just seem to be complaining that Mike McCarthy took his foot off the offense gas, which hurt the offense from moving the ball, which hurt the defense by leaving them on the field more and gave the other team a chance to make the score look closer.
BUT, I care more about the post season... and Mike McCarthy has lost 8 post season games as Packers head coach (4 with Jennings, 4 without Jennings).
In the 2007 Giants NFC Champs game... their largest lead was by 4 points, late in the 3rd, and the Packers were 1 in 10 on Third Down Conversions... that's not taking the gas off the petal, that's the petal being broken. In the other 3 post games loses with Greg Jennings, the Packers either never had the lead, or never had the lead in the last 40 minutes of the game (2009 Cardinals, 2011 Giants, 2012 49ers).
So Jennings seems to be complaining about how the Packers won games, letting the other team have a chance... hurting the players stats/numbers.
Now in the Packers four playoff games without Jennings... (2013 49ers, 2014 Seahawks, 2015 Cardinals, 2016 Falcons)... the Packers have lost the lead in the 4th quarter 3 times. Of course the lead was only above 6 points once... the Seahawks NFC Champs game... which where what Jennings is talking about did bite/hurt the Packers... because Mike McCarthy got into conservative play calling and gave them more chances. But lets no forgot... if the defense made one more stop, if Haha knocked the 2 point conversion pass down, if Bostick blocked and let Nelson catch the ball, or hell if Bostick just caught the ball... the Packers would of won. So that's not all on Mike McCarthy conservative run out the clock play calling...
