Btw, I agree with Brad about the player movement...it often feels as if your players feet are stuck to the ground...in TE 2006 it felt more fluid and bouncy, thus more natural.(and more fun, now it's quite frustrating)
What I really would suggest is making moving in a small area a lot more sensitive, when the player is taking the split steps...Imo the run speed is fine, but I think the player should start running that way(sideways) a bit earlier.
That way it would remain balanced(I think), faster more sensitive split steps, but earlier break into running so that you can't split step half a court.
Another point is that its a shame we don't get to see the new running animation more often(I hardly ever see it during rallies, plus it's more natural if the player runs like that more often).
I really really really think this would work.
Also I noticed this thing...when using the left and right arrow keys, even after stopping pressing them the player moves a short distance left and right. The longer you have pressed the longer the extra distance. I noticed this was also in TE 2006...but now the problem is, because in TE 2008 you have to think about the position, it becomes rather frustrating when moving to balls near the lines to position yourself correctly...you move to the ball, stop pressing while in good position, and yet the player moves by itself further and thus messes up the positioning and hits an error...I know that with practice you might be able learn it better, but I was thinking it would be simply more fun and less annoying if the player almost fully stopped after you stop pressing the direction keys.
