Correct,one of the bigger frustrations for me is that Illegal Screen calls often seem arbitrary.
There are times I don't even have a hand on the sticks yet when I hold the screen button the game decided I should mess up and makes my guy dip into the defender.Other times on defense the CPU can literally be walking sideways while pushing a shoulder into me and no call. This type of disconnect can really make it feel like Illegal Screen calls are just a cheap mechanic the CPU pulls out when it wants one team to go on a run.
