I made this point at the end of the game thread last night, and the only person who responded disagreed, so I'm interested to hear what others think.
I think playing for the last shot when you're losing is a bad, bad, move. If you look for an early shot and it's not there, it's fine to wait. But to intentionally wait dribble out the clock near half-court is nuts. Granted, they shot with enough time to get the put-back, which was smart. I'd happily risk having to play defense for a couple of seconds (given you score), for the chance to foul and get the ball back (if you miss). Besides, shooting with enough time to get a rebound (4 seconds left) means you're going to give the other team the last shot anyway. And 3-4 seconds is often enough time for your opponent to get a good look at the basket or even an easy shot.
Sampson's move is analogous to a football coaching taking a knee three times and kicking a 45 yard field goal on the last play when the team is losing by 1.
Of course, if it's a tie game, playing for the last shot makes complete sense.
