Try 4-3 Zip shoot gut. It's great for stuffing the inside run and leeaving u with coverage help. Pinch line, crash line out, reblitz blitzing LB's and watch em go.
I usually take various plays that have an outside blitzer or two and user contrl the weakside safety. Safeties w\ good speed can catch up to the play quite nicely. Try putting DE's, that are on the side you think he's running towards, in QB spy or contain. This keeps them from rushing the passer and getting stuck in the pile. High rated edge rushers help the outside run period.(J. Allen,Peppers,etc.)
Lastly, try Thunder smoke out of the 4-3 for inside runs. Pinch line, crash line out, and pinch LB's while moving middle LB over DT's left or right hip. High risk high reward yes, but really stuffs dives,blasts,etc.
GOOD LUCK!
