The Celtics are expected to make couple roster moves, waiving point guard Demetrius Jackson and signing rookie forward Semi Ojeleye to a four-year deal.
Jackson, 22, was drafted by the Celtics with the No. 45 pick in the 2016 NBA Draft. He played just 17 minutes for the Celtics last season, but averaged 14.8 points and 6.0 assists with the Maine Red Claws.
Ojeleye, taken with the No 37. pick in the 2017 NBA Draft, averaged 18.9 points and 6.8 rebounds a game in his final season at SMU
Isaiah Thomas appears to be channeling the New England Patriots' "No days off" slogan.
The Boston Celtics guard spent Friday night, in the middle of the NBA offseason, studying film. He was up past midnight to take a look at Boston Celtics' game tape, according to ESPN.com's Chris Foresberg, who posted a picture on Twitter of Thomas hard at work.
Thomas finished the 2016-17 season with 28.9 points per game, 5.9 assists and 2.7 rebounds in 33.8 minutes. He helped the Celtics earn the NBA Eastern Conference's No. 1 seed, and contributed a handful of clutch performances as Boston charged to the Eastern Conference finals against the Cleveland Cavaliers, who won the series, 4-1.
Celtics forward Jaylen Brown joined in the Drive-By Dunk Challenge and tweeted a video that captured his thunderous slam.
We're thinking that's not a regulation height rim.
And the All-Star dunk contest next year might have to be sanctioned by NASCAR.
