SCRAPE EXCHANGE
Say it like this
Quarterback is a few steps back. Stay in your gap and don't guess who has the ball.
What can go wrong
If the LB scrapes late, or the End crashes without the exchange actually happening, the QB keep hits a wide-open alley.
How we fix it
Drill it with a stand-in dummy back so linebackers learn to find the ballcarrier late instead of guessing. This exchange takes real reps to time correctly.

Front shift
The playside End crashes down and takes the dive back, deliberately giving up his normal contain rule. The playside ILB scrapes outside and becomes the new, unblocked QB-contain defender.
Coverage
Base Cover 3 behind it.
Gap changes vs base
- •Playside End: C-gap contain becomes B-gap/dive responsibility.
- •Playside ILB: B-gap fit becomes edge/QB contain.
- •LBs keep reading their normal line key (the Guards) as primary and backfield action as secondary — a pulling guard always outweighs backfield motion.
