1.) Instead of having to choose what superstar your player is, for instance LeBron James, he should have all of his FSS features in game. He can be automatically set on scorer but you should be able to change it ingame, for instance, L1(or the FSS trigger)+any direction on the DPad should scroll through his freestyle options. That way, if you're running on the fast break with LeBron and you want him to do a reverse windmill, simply change him from a scorer to a high flyer.
It's kinda like changing weapons in a FPS. Why shouldn't AI be able to do a double clutch layup on one possession and throw a behind the back pass on the next? Why can't T-Mac go up and under once and dunk on someone the next time? The only thing that could be a drawback is that while changing the freestyle feature, you'd take your thumb off of the left analog which would control the player and make him stop.
2.) How about some freestyle superstar dribbling moves. We have triple threat moves, but why not some crossovers and stuff? Ball handling is an important way of freeing up a shot. Look at DWade, he should be able to pull some electric crossover moves, not the same ones as Jiri Welsch.
And possible some "broken ankle" animations. It should happen rarely, but the defender could anticipate wrong and run in the wrong direction.
And in dunk on animations, they don't have to be big time crotch in face slams. EA should incorporate some like "dunk bys" like Dwyane Wade had last night. Not necessarily alot of contact.
