Most of what I would like to see in Madden 11 involve mechanics:
-Downfield blocking as I mentioned in the review
– QB being able to lob the ball off when being sacked. This can be
remedied by playing with the tuck rule. Have it so the QB doesn’t
make forward movement with his arm every now and then,
resulting in a fumble.
– Both quick release and play action for QBs have some work that
needs to be done. A “quick pass” rating for example may remedy
this. Inaccuracy of QBs right off the snap or play action is quite
unrealistic in terms of accuracy.
– Wildcat plays need to be nerfed. They are way more powerful than
realistically possible.

Feature wise I would like to see what NBA games did last year with integration with the season. Obviously they do a great job of roster updates each week, but I want to see team tendencies be tweaked. For example, a team averages 8 penalties a game and is going up each week. I want to see that team be more penalty prone in Madden. Or a team for the season is right side heavy with 75% accuracy on that side versus 40% accuracy on the other. I want to see right side play accuracy increase.

I would also like to see co-op mode be fleshed out some to do a better job of aiding to “noobs.” An online co-op versus mode might be nice too.

I do think that a DNA, as NBA Live has called it, would be a big selling point for hardcore football sim players like myself.
