Or should I say, GROW UP! There is no emotional, feel-good answer to sidestep fundamental defensive football. There is no kickass defensive scheme that has 9000+ hit points that annihilates offenses. Your defense must be built on a solid foundation of coverage, run support, and assignment keys - they are all one and the same.
Your genius plan works against 2-back pro? Awesome.
So does Oxyclean and banana peels. What happens with twins, with trips, with 1 back, with no back, with unbalanced? What is the adjustment and is that adjustment congruent with what you are already asking your players to do? If not, its time to shake the Etch-a-Sketch.
Want to start sending people?
Want to do wacky things with stunts and load up the box?
Want to reposition / realign your players?
Great - go for it.
Just be sure the entire 11 man defense has an answer to adapt. How drastic of a change is it? Can you remain the same 'defense' you are? Does it require you to alter your run support / coverage? If so, CHANGE it (or don't run it).
If you make the change, how can an offense break you? The stars most likely will NOT align for you on game night. Coordinators are not as dense as you. You will be exploited. How do you intend to respond?
Coverage Determines the Front!
