Your team is ahead by 2 with 15 seconds on the clock.  Your
   opponent has the ball.  Are you going to play out the defensive 
   possession or are you going to foul?

   Obviously, you do not want to foul a shooter.

   Have you practiced the unintentional intentional  foul?  In other
   words, do your players know how to commit a foul  without it 
   looking like it is intentional?

   Do NOT get beat by their best three point shooter.   Deny
   him/her.  If you are going to get beat, get beat by someone else
    than their best shooter.

   If you decide to play out the possession,  you must secure the
   rebound.  The old adage ... "You don't get beat on the first shot.
   You get beat on the second shot."  Can happen.
   
    Know what the team foul situation is.  Know who the poorest
    free throw shooters are.   If you can leave the poorest perimeter
    player open,  then foul immediately on the catch.  If your plan is
    to foul.

     If you foul, and free throws are awarded, make sure you match
     up on the free throw spots.  Keep their best offensive
     rebounder from getting the rebound on a missed free throw.
