There's been a couple threads about defenders rushing the passer leaving their assignment, I made one of them.
I'm on PC and I moved the right stick click to select and this stopped happening, it's not mentioned in the controls but it's a "hey, someone go after the QB" button that was put in awhile ago, but I thought it's been removed for some time but apparently not, although it's not in any of the control screens.
I'm dedicated however they're using some light sensitivity of the button, when I suspected this I went into GTA and flailed the right stick all over the place and it never looked behind me (it's function in GTA) unless I really pushed it down, however in madden it seems to trigger just moving the stick down and to the side almost like clockwork. I figure and am pretty sure it is only a on or off button, but I tested this extensively in both games and can get it to happen constantly in madden so I'm still a bit perplexed by it.
They really really want people usering linemen this year and it's an apparent issue I had with both an xbox and ps4 controller on pc
