PHILADELPHIA — Joel Embiid returned to a rousing ovation from 76ers fans in his first game of the season, a start marred by injuries and suspension to the All-Star center that kept Philadelphia anchored at the bottom of the Eastern Conference.Embiid wasted no time giving the Sixers a tantalizing glimpse against the New York Knicks on Tuesday night of what could be — a dish to fellow oft-injured All Star Paul George for a layup to open the game.“He’s looked good,” 76ers coach Nick Nurse said of Embiid before the game. “He’s done a lot of work to get ready here.
