Philadelphia 76ers rookie Ben Simmons recorded just one point in 31 minutes of action in Boston last night, something he contributed to "overthinking." Simmons only took four shots throughout the entire game and turned the ball over five times as the Celtics overcame a 22-point deficit to take a 2-0 lead in the series.

"I think it was mainly what I did to myself," Simmons said, according to ESPN, after failing to score a field goal for the first time in his 87-game career. "Mentally, I was thinking too much, overthinking the plays. Wasn't just out there, flowing, playing the way that I play, which is free.

"I think, obviously, [the Celtics] have a game plan, I know what their game plan is, and I've got to play my game."

Boston was physical with Simmons in Game 2, limiting him to just seven drives to the basket, according to ESPN Stats & Info. Still, Simmons says his 1-point performance was more self-inflicted than anything that the Cs threw at him.

"Mental, thinking too much," the Rookie of the Year candidate said after setting a career low for points. "I think the way the Heat played [against Simmons in the first round], it was nothing compared to the Celtics. Physically, the Heat were on another level."

It'll be interesting to see how the rook responds in a pivotal Game 3 in Philly tomorrow night.
