1 is in a defensive stance 4-6 feet away from coach (or another player) who has a tennis ball in each hand and alternately tosses a ball to the left or right. 1 slides to catch each ball before the second bounce, tosses it back to coach, and slides back to his starting position. Coach should vary the distance, direction and speed of each toss, not leave time for rest in between, and not always alternately toss left then right. Go for 8-12 seconds, 3-4 sets with 40-60 seconds between sets.
Allen Stein - 1 alternates tossing two tennis balls.
Alex Daniltchev - 1 alternates dropping two basketballs while both players move upcourt, then lobs passes.
