Scheierman took his occasional blowout minutes with Boston, and, mostly, honed his game in the G League with the Maine Celtics. He has averaged 20.4 points there, and has shown why, exactly, Boston picked him in the first round: He can shoot.

Scheierman is shooting 41.1% from the 3-point line for Maine.

He had trouble translating that to the NBA, though, as he was just 5-for-25 from the 3-point line in his scant 143 minutes of rookie action. That changed on Tuesday, though.

While Scheierman has been getting more minutes off the bench lately, with both Jaylen Brown and Jayson Tatum out in Boston’s home game against the Nets, Scheierman had his best-ever outing. He went 6-for-7 from the 3-point line, scoring 20 points.

His best moment came on an in-bound play to close out the third quarter. The Celtics were trailing, 70-68 at the time, and Scheierman knocked down a 3-pointer at the buzzer to give the Celtics fourth-quarter momentum. He made three more 3s in the final period to help drive the win.

After the game, Scheierman said, “When I hit that buzzer-beater and the crowd was going crazy, that was probably a top-three environment I’ve ever been a part of.”

And the Celtics commemorated the moment with a post captioned, “Baylor loves Boston.”

Coach Joe Mazzulla said he was as impressed by Scheierman’s defense as his shooting. He appreciates, too, Scheierman’s willingness to wait for his chance.

“He’s got high level toughness to him. He’s got a good basketball IQ. To me it’s just the consistency and the patience,” Mazzulla said. “You can’t get discouraged. You’re not defined by one day, two days. It’s really just a process and the small moments you have, you’ve got to take advantage of them.”
