The above picture is from the Green Bay Packers goal line stand on the closing play against the Saints that ended the comeback attempt. What I recall was a lot of Saints going down, and a lot of Packer defenders converging on the ball carrier. 

Ben Muth knows a lot more about blocking and offensive lineman than I'll ever know and he took a closer look at this play. From Football Outsiders:

What killed the play was the guy lined up at right tight end: [backup OL Charles] Brown. The second-year offensive tackle stepped inside and then promptly fell on his face. Literally, that's all he did. I expect to see a picture of him planking during an NFL game on Twitter any day now. As a result of Brown's dive, both Matthews and Morgan Burnett knife inside and t-bone Mark Ingram as he left the ground.

The entire article is interesting if you're looking for some very in-depth analysis on how the Saints offensive line performed against the Packers.
