1. Make the players actually run like real football players.
2. Physics to actually be respected
3. No more sliding around on the ground like they are on ice
4. No more turning instantly
There are a ton more flaws I see with the game but they still have yet to get the fundamentals down. I want the fundamentals done right before we add the other minor things like you mentioned. People seem to ignore the lack of realism the game has had for the past 5 years thanks to this monopoly like NFL license they have.
