the only advice i can give u is to foul him.. remember foul will not be recorded. so inorder to foul him. u hold u L button which is the juice button with the additional of A button the quick steal button!.. so L+A to foul him. he will lose the ball sometime.. and also.. if u are running out of time.. try to tie up with the player if the player is ahead or catch up to be tie with the player if your behind. so you could have more time to steal 5 times.

just use your speed and steel it once, then remember that you have four fouls to give so just foul him four more times so he looses the ball, that will be five steels in all then just win him to 21 or whatever........
