Joel Embiid scored seven straight points to make it 96-95 and finished with 24. Jaylen Brown had 21, and James had 17 points and 10 rebounds in what ESPN's recap calls the biggest comeback win of his career.
Cleveland's questions
The James subplot makes this one sting. Cleveland was one of five finalists James considered and the only one he visited, according to ESPN, before he signed a two-year, $8 million deal with Philadelphia. Coach Kenny Atkinson said before the game that when a move like that falls through, "you're depressed, quite honestly." The Cavs pivoted to a five-team sign-and-trade for Peyton Watson, who had eight points on 2-of-7 shooting in his debut.
Even the lighting took heat. The AP noted that a new system at the Sixers' arena gave the ESPN broadcast a blue tint with heavy streaks and reflections.
What to watch: Cleveland's home opener Saturday against Brooklyn and whether the 3-point shooting recovers after a 24% night. Philadelphia, 2-0 with wins over the Knicks and Cavs, hosts Milwaukee on Saturday and Detroit on Sunday.
