I have a question...

Ok, i play NBA live for xbox...Sometimes when i dont feel like playing my dynasty, i go to individual practice to shoot around...well, i just found out that i can do alley oops to myself off the backboard.so i went to play a game with the spurs against the lakers and i press the button to do alley oop to myself and it doesnt do anything..

Is it possible that u can do alley oops to yourself in practice ONLY?
Thanks

you can do alley oops in all star games as well, but not during regular games

THANKS A LOT!!
