I haven't had one single RB screen pass go for any more than tackled at the line of scrimmage. As others have said, 3 blockers will completely miss on the lone defender. I get lardass defensive tackles sticking to my RB's out of the backfield like white on rice, blowing up my plays for negative yardage. Several times I've had RB's get stuck in the pass rush, not even making it out to the flat. And the rest of the time, the free rushers get in so fast, and the QB throwing animation is so sluggish, I end up eating the football during the throwing motion.
