That's one thing I have NOT noticed on All-Pro. Now, for ex. If I highlight the TE and they have a WR running a streak next to the TE, my safety will abandon his deep assignment to go cover the TE underneath, which could lead to giving up a deep pass.
I have yet to see my defenders moving out of the way or running away from the ball carrier like M15 did.
Only 4 out of my 17 games have been blowout wins by me. The rest have been decided by 7pts or less, and I was blown out a couple games by the cpu. So far it's been really well balanced but it has more to do with how I call a game and keep it more coach mode.
If I called my own plays and put more user manipulation into it, I would need to adjust more I'm betting.
