The Boston Celtics star forward Jayson Tatum was quick to take ownership after the Celtics let the game slip away in their 119-115 loss to the Philadelphia 76ers in Game 1 Monday night.

“I guess,” said Tatum on if the Celtics missed an opportunity. “S***, you want to win every game you play, regardless of the circumstance. You want to win. And we didn’t do enough to win. Every game you lose is a missed opportunity to get a win.”
