This is a concept I saw many times throughout the season, and it's simple in what it tries to accomplish. There's a common idea that Kyle employs when using his RB out of the backfield to attack the flats. See if you can notice it.
49ers have identified man coverage here and will run a mesh concept directly over the short middle of the field where there are many bodies. The green/red/orange routes all work to the opposite side of the field while the RB out of the backfield works to the wide side of the field (based on spot of the ball on the hash).
Blue LB has the RB in man coverage. Just looking at the routes, we see that blue LB has a lot of traffic to work through in order to cover the RB.
vs Cover 1 blitz
The LB is already behind the play, and has ground to makeup in order to cover the RB never thought Breida would release to the opposite side.
With the RB immediately releasing to the opposite side of the formation, there is too much traffic in the box for the LB to get through. Easy conversion.
------------------
Same idea. This is against a pattern match Cover3.
Three routes from the strongside of the formation run to the opposite side of the field. Defenders match. The "goat" on this play is the strongside C/F defender. He matches the route of the #2 and abandons his curl/flat area.
The RB having to reach back for the pass eliminates the opportunity to get RAC. Still got the 3rd down conversion.
-----------------
More of the same. vs Cover 1 blitz. There's a blown coverage because the LB that's supposed to cover Breida.
This idea of releasing the RB to the opposite side of the formation really tests the eyes of the box defenders. It's not often that a RB lines up to the left/right of the QB, then releases by crossing the QB's face to attack the opposite side of the formation. In all the plays above, and most of the plays to be shown, the RB attacking the flat will attack the wide side of the field. There's more room to work some RAC this way.
