If you are a smart player, either clanking them or watching your team mate clank them, you learn how important all those possessions were earlier in the game when silly turnovers occurred because of bad passes, or thoughtlessness. You remember all the pour choices taking bad shots. You remember times you coasted a little bit and some guy from the other side blew by you and made the basket while you fouled him with a lame attempt at a block. You think about the moving screen you set that gave the ball to the other side. And you learn.
Silly to expect the Raptors to win this game. Good that they were in it into overtime and it took a hail Mary with .2 seconds left to take it away from them.
