I would also like to know what makes QB's hold the ball. In my experience raising WR catch made them hold the ball longer. I heard lowering QB accuracy also makes him hold the ball, and now I hear pass rush has an effect as well. Everytime the QB does that "step up and wind up deep throw" against me; I sack him. (My pass rush is at 20 and CPU pass block is at 20, with thier QB Acc and WR catch slightly above 50)
