This looks kind of interesting to me, but I think I'll pass. I have a feeling NCAA 07 will be a better fix untill matters comes than this (despite the $20 extra) but I can get it for 360 instead of regular XBOX.
The link above is a link to a thread on an EA message board for this game. It explains how the practice system will constantly drop your veteran's ceilings on their overall rating if you actually play the practices. If you simulate them, their ceilings will rise, but the rating will stay in the low area. This explains why players like Will Shields, Alan Faneca, Jeff Hartings, and other players that are 30+ and have high ratings that will constantly drop during the season if you actually play the practices. As far as I know, the only solution is to simulate the one-on-one drills and to play the off vs. def drills. This could possibly salvage my season, but it could save yours if you just started.
