Ok, you ran PA, and when your QB was set you ran backwards 7 yards and threw it off your back foot. So what would have been a 15 yard pass from QB to WR, turned into a 23 yard pass off your QBs back foot, and you're saying bull shit? If ANY QB in real life were to run backwards and throw from 12 yards behind the LOS every CB in the league would be jumping those passes for INTs. Try stepping up into the pocket and see what happens.
