Just to clarify the AM / AP "Level Blend":
It's a great option to have access to, if you (or the team you're playing as) can't get reasonable production / stats...
It works especially well for lower rated teams, rookie or mediocre QBs, teams with Confidence hovering around default, etc...
However, if you find yourself (like me) having your team OVR go up a few points over a couple seasons and have Confidence hovering closer to "max", then you're prob (like me) going to want to go back to AM in BOTH the Main Menu and inside CCM...
Otherwise, the sacks creep back up a little and it becomes a little "too easy" to move the ball on offence...
Well, that's been MY experience with this title...
So:
For my "Confident / 86 OVR MIN team with a progressed QB, it's been the way to go (back to):
AM in the Main Menu / AM inside CCM / Gameplay Tuning: ON
