Idk if it's been said or not but before you pick a play click down on your right stick to bring up the defensive adjustments menu and change tackling to aggressive as well as strip ball to aggressive. Regardless of how good your team is it should help you get a few more fumbles. Hell when I play solo seasons (usually only done for challenges) I just call field goal block every time on defense and get hella sacks and fumbles but to be fair I do have a stacked team.

I’ve been more successful with this and as my team has gotten better def more difficult than Madden
