Defense is the worst is as ever been for any Madden game ever. An embarrassment to the sport.
Defenders do not react to the ball and they pursue ball carriers by animating towards their side and do not attempt to cut them off by moving at an angle that would cut them off as they are moving downfield like what realistically happens.
Zones are awful. Hardflats do not play the hardflats. The best run defense is dollar dime defense which makes absolutely no sense at all. You removed sheds for whatever reason so the qb is never under and pressure and the offense is coded to be faster than the defense no matter what so they will always eventually get open. The AI defenders do not play the ball. They watch it fly over their heads though. When defenders play zones, they ignore and receiver that is not directly next to them so they stand in their zone yes, but obviously they should be looking to play the opponent that enters it instead they just stand in place watching them catch the ball. I can go on an on. Professional comp games regularly go to 50+ points for each team since nobody can stop anybody. The game comes down to who can grind out the most clock successfully rather than actully making stops on defense since it is basically impossible. This must be fixed.
Make the defenders faster than the offense if you can’t figure out how to code them correctly to react to the ball at the very least.
