Joel Embiid had an awry night against the Boston Celtics, as the Philadelphia 76ers big man was haunted by his grim reaper, Al Horford, throughout the game. One particular play in the dying seconds of the game, while the Sixers were trailing by three, saw him put back a missed shot to make it 110-109, squandering any chance of a potential tie with that crucial mistake.

I’m an idiot,” Embiid said, according to ESPN’s Tim Bontemps. “I should’ve kicked it out or took it out and shot it. I didn’t think about the situation and us not having a timeout. I thought we had one, and as soon as I shot it, I looked and said, ‘I’m stupid.’

“But, like I said, that’s on me. I need to do a better job.”

Joel Embiid still had a decent night with 23 points, 14 rebounds and two blocks for the night, but was mired in foul trouble and frustrated by Horford, who got an easy 23 points at the other end, with plenty of defensive plays to boot.

The Sixers’ big man put the fault in his very own shoulders, claiming this wasn’t something Horford got underway, but his own lackadaisical approach in this game.

“He’s not doing anything,” Embiid said when asked about being guarded by Horford. “I was sleep-walking for three quarters, and that’s on me.

“Like I said, that’s on me. It had nothing to do with anybody.”

The new-look Sixers still proved incapable of conquering their demons and lost to a Celtics team that has lost the last two games against a puzzled Los Angeles Lakers team and a hollowed-out L.A. Clippers, a head-scratcher at best.
