Instead of watching the guy covering the ball tonight on defense - I watched the other perimeter defenders. When the opposing player makes a move with the ball the other perimeter players immediately react towards the player with the ball - going for a steal, trying to help, or more commonly just drifting closer to the play. The opposing guard then just kicks it over to the open man for a 3 ball. Our perimeter guys need to stay put more and stop over-reacting so much.
