I've been so into player creation that I've had very little time to play and experiment.The one thing I did do was lower linebackers coverage by 5-10.I offset this rating by boosting consistency a little.The linebackers coverage being lowered has made the computer's short passing game a little more effective IMO.
I certainly didn't want to do anything drastic.Most players are the same and only a small amount were changed slightly.I didn't want to put too much stock in pre-season.
