The playoffs opened with three upsets, but nobody had a worse day than the Sixers, writes Michael Lee of The Athletic. Philadelphia’s problems go beyond the final score, as nearly every fear about the team heading into the postseason came true. Joel Embiid‘s sore knee, Ben Simmons‘ limited shooting range, the lack of a bench, defensive concerns and chemistry issues were all on display as fans booed loudly in a loss to the Nets.

Some observers believe the Sixers compiled the most talented starting unit in the league by trading for Jimmy Butler and Tobias Harris, but those five players only took the court together 10 times in the regular season. And with Butler, Harris and J.J. Redick all headed for free agency, the team could easily break apart if the postseason doesn’t go well.

An even greater concern might be Embiid’s physical condition. Bothered by tendinitis in his left knee that limited him to eight games after the All-Star break, Embiid wasn’t sure if he could play until 15 minutes before Saturday’s contest began. He lumbered up and down the court for much of the afternoon, settled for outside jumpers and was frequently targeted by the Nets on defense.
