This is our discussion on defending RPO’s from the 4-2-5. Here I run a check I learned from Coach Gray when he was at Virginia Tech (now at Florida), and another I’ve borrowed from Hugh Dehnert (Tampa Plant) and Sean (@IMFB_Sean).
You can see above how we would adjust to a 2×2 set. To the field, we will play the Sam heads up on the slot, and the CB 5 off and inside of the outside receiver. The FS plays the apex about 6 yards deep. On the short side, the CB is at 5, the boundary safety plays 6 deep too.
You can see the way we defend a 20 personnel offense here. The CB is 5 off the outside WR to the top, the slot is pressed by the Sam, and the FS is in the apex. On the bottom of the screen you see the CB at 5, and the boundary safety actually walked up in the box (another check we can use) but the important part against the RPOs is taking the bubble away.
Here is the way we defend RPO’s against trips. The CB is still at 5 off the outside WR, the Sam over #2 pressed, and the FS at the apex between #3 and the EMOL.
The coverage idea is below:
The CB plays tight to the X, and the $ will help over the top. The SLB runs to the bubble while the trips side CB jumps the slant and the FS fights the stalk to help with the slant and play the alley.
Above is “trap” coverage where the CB to the trips jumps the bubble, the Sam bails and plays the slant and the FS fights off the stalk to play the slant and alley.
