Audibles and Strategy

Ok, so I have improved my D. Learned some good blitzes out of 3-4 and 1-1-5. My question is what are some good plays that you can set up to look like your blitzing in these formations that will get good coverage? Seems like I get burnt with C2 up the sideline and deep middle. C3 get burnt in the flats. Any setups out of 3-4 or 1-1-5 that would cover as good as say Velcro or max zone?

anytime you blitz someone your leaving holes in your D you just gotta be smart and inventive, dont be a machine, adjust to the areas that your OPP. is attacking, i dont think theres a blitz in the game that covers everything, but it doesnt need to ya know? the heat should get there before they can really do anything big, be confindent that your heat is gonna hit home.

I gotcha. I know there will be holes when I blitz. What Im trying to find are plays out of the same formations that I can switch to and confuse my opponent. Any C2, C3, or any play for that matter that gets good pass coverage? If so, what are the adjustments?
