I learned this from a pro player, you can try for yourself. This year in madden there is an underwritten code for QBs to be more inaccurate while outside the general pocket or if theyre moving at all. So when you throw the ball if you’re moving anywhere BUT up towards the center it’ll be less accurate. So if you’ll about to throw a med/deep pass step forward in the pocket (towards the center) and then throw it and it’ll automatically be much more accurate as compared to if you’re even just standing still . For some reason you gonna step forward and then throw like in real life
