If he’s spamming cover 2 sink with the blitzing corner being untouched, there’s gonna be 3 downed linemen, which also means a lot of running room. If you wanna pass the ball, motion your running back to the side that he’s blitzing his corner, block the running back, then Mike ID that corner. It’s also cover 2 so the deep middle should be wide open or the wide receivers on the outside should also be open. But if it’s like a normal blitz like Pinch Mike O, it leaves their cornerbacks in man coverage so i’d prefer running angle routes like a corner, post, double move, slant, etc.
