In a word, REALISM.

All penalties. Realistic amount of penalties. Many penalties aren't even in game.
Realistic amount of INT's and fumbles. WAY too many INT's this year.
Realistic kickoff/punting distance, coverage and return.
Realistic injuries. Lineman never get hurt. If someone gets hurt during a play you should see them pull up in the case of a hamstring injury, etc.
QB's are too accurate. Sliders must be put very low to actually see overthrows/underthrows.
WR's catch balls after taking big hits too often. WR's should drop more balls on big hits but there should also be defenseless reciever hit penalties.

EA - look at average stats for NFL seasons and model the game to return realistic results. The focus on line play was a step in the right direction. Keep up the under the hood fixes. We don't need flash, we need a football SIMULATION!
