So, the 1st play of the game was a nice completion to Sanders for 48 yards. The Broncos came out in Detroit personnel (2TE2WR1RB) with a trips to the field.
The Chiefs aligned (as they love to early in games) in their "Reduce" front, which is base 3-4 personnel. The front looks like this:
If you'll notice, it states that it's a either Cover 3 (Trey) and Cover 6 (Pack) depending on the offensive alignment. The front can also change by alignment.
In the picture above, you'll notice the left end has changed from aligning in a 4 technique or heads up on the offensive tackle to aligning heads up on the "Y" or TE. The other DT has changed from a heads up "2" technique to a 3 in-between the guard and tackle. It looks like this in the Jets PB.
Now, in the picture above, you'll notice Cooper has now changed to playing off coverage. Because of the front change, the chiefs are now playing "Pack" or Cover 6 with the quarters side to the field. Cooper is responsible for 1/4, Berry 1/4, Abdullah 1/2, and Smith squatting on the boundary side.
In the picture above, you can see the 2 vertical routes getting ready to rape the quarters coverage. Berry will pick up Thomas, leaving no help for Cooper. Thomas draws Abdullah as well, leaving nobody over the top to help Cochise's favorite player of all time, Marcus Cooper.
That results in this picture below:
Steve Spurrier was pretty well known for his "Mills" concept: a 2 man combo that had the inside receiver running a deep in/dig and the outside receiver running a post. Against quarters, the inside 1/4 player jumps the underneath route and the post is 1-1 with inside leverage.
Peyton Manning used it pretty well here.
. Just found this. Same. Exact. Play.
