If you're spamming the play ofc it's going to be taken advantage of. Every play has a time and place where it can work. as for good run stopping plays, any of the 4-4 plays where one of the ILB's comes down and one of the olb's comes down. Zone works best because it holds the CB to the outside.
I've been having pretty solid success stuffing the inside run with 9th Planet by stacking the box with man coverage LBers and Safetys. We get burnt on the outside somewhat though
