One tool that sat in the pockets of the Eagles' defensive linemen and was very effective for them on Sunday was the use of stunts. Whether it was a simple "T-E" stunt or a basic "E-T" stunt, the Eagles were able to have success. What is the difference between the two?

On both stunts, one player shoots upfield first as a penetrator, typically attacking a shoulder of an opposing offensive lineman. When one is used as the penetrator, the other is used as a "looper," running around the penetrator into the opposite gap to get into the backfield. These kinds of "games" up front can create confusion for offensive lines. The schemes typically work to open up a lane for the looper, but sometimes it's the penetrator who actually gets home. In the clip above, we see examples of both scenarios, as Jernigan gets a sack as the "penetrator" and Cox gets a tackle for loss as a "looper" on a draw play.

The Eagles' defensive line has a big opportunity against Atlanta to wreck the game, much like the Minnesota Vikings' group did this past week. It will be one of the most pivotal matchups in the game. I think the Eagles will be up for the challenge.
