Yeah, if your opponent is playing a pass defense then do what's necessary, which is run the ball. I understand that you wanna be sweet and pass the ball every down, but when you gotta win, do what's smart. Against dollar cover 3 thats run, or you could send your outside receivers on fade routes and rocket catch to beat cover 3. When I see that safety drop down to signal cover three, I hot route and wait till the receiver goes downfield about 20 yds, then throw a bullet pass and rocket catch in front of the cb.
