Instructions
Delete your current game save data. To do this on the PlayStation 3, go to "Game Data Utility," select "NBA 2K10" and press "Delete." On the Xbox 360, go to "Console Settings," "Hard Drive Settings" and "NBA 2K10" and press "Delete."
Start up your NBA 2K10 game. The game will ask if you would like to install the latest firmware update. Select "No."
Bring up the Quick Menu and select "My Player" from the Franchise menu. Then select "Edit Player."
From the "Edit Player" screen, bring up the Quick Menu again. Select "My Drills."
Run a drill with the player from this menu. The type of drill is irrelevant.
Play through the drill as usual. Your performance in the drill will determine how many skill points you are awarded.
Return to the "Edit Player" screen. Your player will have gained skill points, but will not have expended any of his remaining drills (or "drill points").
