Instructions
Pick a player with a high speed and block rating, because you'll need to overtake the opposing player moving to the basket.
Chase down the player at full sprint, avoiding other players who block your path.
Drive toward the basket with the expectation that the opposing player will try a dunk, layup or short jump shot near the hoop. Approach him from the rear or the side.
Press "Y" to block as your opponent begins to take his shot.
