Teodosic then stepped back as the other Serbian players spread out wide, dribbling the clock down as he stood 28 feet away from the basket. Garbajosa played off him, and with five seconds left, Teodosic let it fly. And when his straightaway 3-pointer went through the net with 3.1 seconds left, Serbia had a 92-89 victory that dethroned the defending world champions. “In the timeout, we decided we would only shoot a long 3-pointer. If we miss, it’s overtime,” said Serbian coach Dusan Ivkovic, whose team avenged a defeat against Spain in the gold medal-game of the 2009 EuroBasket tournament in Poland.
