It's my feeling that EA tweaks the game tuning once a HUM STICK is in the game. The booth COACH mode does not seem to exhibit the same psycotic LB abd DB game play.
Playing on AUTO-PASS should still be detected as a HUM Stick and the defensive agressiveness may be adjusted accordingly. But you are in a better position than I to tell us ?
Do the LB's make incredible changes in direction and is pass coverage monsterous or not? There are plenty of threads discussing the questionalbe defense reactions .. are you seeing them?
