Furkan Korkmaz was the hero as the Philadelphia 76ers preserved their perfect record in the NBA with a dramatic 129-128 win over the Portland Trail Blazers. Korkmaz made a clutch three-pointer with 0.4 seconds remaining as the unbeaten 76ers improved to 5-0 for the season on Saturday. The Trail Blazers had led thanks to Anfernee Simons' three 2.2 seconds from the end in Portland, where Korkmaz stepped up by hitting the game-winner as he fell to the floor.
