Would be nice if some how we could spectate a game, especially for us that play in leagues. Pretty much just like quake or something... I know live doesnt use a dedicated server, but maybe something like this is possible.
Also, at halftime or end of game showing a great play replay. (didnt lakers vs celtics have this)
Making not all blocks go out of bounds or across the other end of court.
Making the only way to get a charge to hold button down. Charges are in NBA are called also when guys aren't in the position. (frustrating when online or with a friend and they just turbo run you over.. and no call)
