Mike LB RTG issues

I’ve had a blast playing MLB in RTG. Freshman year at Alabama worked my way up to MLB1, and it was so much fun. Sophomore year, new coach, and I’m assuming because it brought his playbook, but about 80% of the game I will be placed on the defensive line. I will change defensive scheme before each game to try and combat this, but it just reverts back to nickel almost every single time. It’s not fun and almost unplayable. I wouldn’t mind it doing every once in a while but I’m just stuck on the line and it’s killing my stats and my enjoyment. Any ideas?
