In the last game I set human run block to 15, since in the OP you have 9 (-6) which I'm assuming means it used to be 15. The game felt a little better, like I at least had a chance. I broke an outside run for 15 yards.
I haven't played Madden since '16 and I've been playing old NCAA games a lot. I think there will just be an adjustment period for me and was hoping to start the run block slider out a little higher and work my way back down to 9. The pass game feels spot on to me.
