The last couple of basketball games I've been working on an old technique to try to capture the motion of the game. This involves slowing the shutter speed down and panning the camera with the players. The hope is to get the player in focus, but those things that are moving fast will be blurred. In basketball that will typically be the hands and feet. Panning the camera also adds a motion blur to the background.
The down side to this technique is that you need to be sitting along the side of the court, which means that you miss some of the action under the basket. Obviously, the up side it that a new level of action is introduced into the image.
