On Monday, with the NBA's moratorium on business lifted, the blockbuster trade of Jaylen Brown from the Boston Celtics to the Philadelphia 76ers became official. 

Thus ends the 10-year chapter of Brown in Boston, where he rose from the No. 3 pick in the 2016 NBA Draft to a five-time All-Star, a two-time All-NBA selection, an NBA champion and an NBA Finals MVP.

Brown helped the Celtics go 56-26 this past season, largely without Jayson Tatum. He finished sixth in the NBA's MVP voting after averaging 28.7 ppg, the best average of his career.

The Celtics' leadership group is expected to meet with the media on Monday afternoon (4 p.m. ET) to discuss the Brown trade - and the direction of the franchise - but Brad Stevens put out a statement about Brown in an official press release about the deal.

"Jaylen Brown will rightfully go down as one of the defining players of this era. Like the best Celtics before him, he is a terrific player and has also had a huge impact off the court. On a personal level, I am thankful to have had a front row seat to the first 10 years of his illustrious career. I could go on and on, but a few sentences, paragraphs, or even chapters wouldn’t do it justice. His legacy as a Celtic is forever etched in stone.”

Stevens is certainly right, and when the dust eventually settles, there's a chance that Brown will have his No. 7 retired in the rafters at TD Garden some day. In addition to winning a title and becoming NBA Finals MVP, Brown was also an Eastern Conference Finals MVP and helped the C's to another championship series in 2021-22.

As of this moment, we still don't know the prime motivation for trading Brown, but perhaps those answers will become clearer when Stevens and owner Bill Chisholm meet with the media on Monday.

Stevens has a unique perspective on Brown, considering that he was also his head coach for the first half of his career. Stevens stepped down after the 2020-21 season and transitioned into his current front office role.

The NBA, and the Celtics, by extension, are set to test out one major potential rule change in the looming NBA summer leagues, which began over the July 4 holiday weekend.

The Celtics won't take the floor for the first time until July 10 in Las Vegas, but this rule will be fascinating to watch play out.

According to the NBA, the league will be testing out giving a single free-throw to players, regardless of whether the foul was a one-shot, two-shot or three-shot foul. 

The foul shot will be worth the same amount of points as the foul was for. For instance, if a player is fouled on a three-pointer, that player will get one foul shot instead of three, but that one foul shot will still be worth three points.
