Explanation for the difference between All American and Heisman

I would like to know what EA Devs notate as the difference between user game play when playing one another on All American vs Heisman settings. 

In the past, and on Madden, it seems the higher the setting, the more the "AI Helps".

So by playing on Heisman, a coach is essentially playing vs a coach, and the AI Adapts / learns around you to help out. 

So an OVR 80 team, vs an OVR 92 team, each being coached on Heisman, those CPU players will play to their proper AI levels, adapt, and learn. Preventing things like ISO up the middle over and over without the DLine adjusting / adapting. The Heisman setting hurts coaches that tend to the run the same base 4 - 6 plays over and over. Stops PA from working when there's not a run game, etc. 

Is this the case or not? All American appears to allow the higher OVR team to just put it in cruise control. Run to the side the user is not manual, and take advantage of the weak AI adaptation. 

Could  EA / or a DEV respond. Not interested in players "perception", interested in how the game was built and what the intention was / is between those two settings. 

Thank you
