Jaylen Brown said he wasn't sure if owners would fully back players in supporting their social justice movement.

"I'm not sure. I can't speak for everybody. I can only speak for myself, and I am not sure. I'm not as confident as I would like to be, I'll say that," said Brown.

Brown added that he's skeptical of small, incremental changes, as the same issues continue to persist in 2020.

"Everybody keeps saying, 'Change is going to take this, change is going to take that.' That's the incrementalism idea that keeps stringing you along to make you feel like something's going to happen, something's going to happen. People were dying in 2014, and it's 2020 and people are still dying the same way. They keep saying 'reform, reform, reform,' and ain't nothing being reformed. I'm not as confident as I would like to be."

Brown previously lead a protest in his native Atlanta while the season was suspended. 

Brown said that NBA arenas becoming voting centers was a start of a process, though he wanted to see all 29 arenas involved.

"Voting shouldn't be this hard. It shouldn't be this much of a disconnect between. It should be something easy. And yet, there [are] less and less voting polls in certain communities, less and less workers in certain communities. And it makes it extremely difficult. It's difficult, it already is already. It makes it even more difficult to get outside and vote. So, I would like to see every NBA team that regardless of what was agreed upon ... open [their arena], and I would like to see more players and athletes, people of influence, bring it to their cities to kind of combat that."

Players from the Toronto Raptors and Boston Celtics met on Tuesday evening about the possibility of boycotting Thursday's Game 1 of the Eastern Conference Semifinals and other measures following the shooting of Jacob Blake by police in Wisconsin, a source told Marc J. Spears of The Undefeated.

“Brad is an accomplished coach and an outstanding person,” said Boston Celtics Lead Owner and Governor Wyc Grousbeck. “We are proud to have him lead our team forward in our quest for Banner 18.”

“We are thrilled that Brad Stevens will continue to be our coach,” said Boston Celtics Co-Owner Steve Pagliuca. “He has become one of the best coaches in the NBA, and is a real leader on and off the court. This is a great day for the Boston Celtics.”

“Brad is one of the most intelligent and hard-working coaches in the game today,” said Boston Celtics President of Basketball Operations Danny Ainge. “More importantly, his character and integrity have contributed to a culture that we all highly value here. Brad is a great teammate, and a leader people want to follow. We are honored to have him with us as we continue to pursue our next championship.”

Kemba Walker admitted that he seriously considered signing for the New York Knicks last offseason.

"At one point, yes, yes. Before Boston actually came along, the Knicks was one of my top priorities, actually, because I was thinking that they were gonna get another player. But it didn't work out," said Walker on the R2C2 podcast.

Walker did not elaborate on who the other player would have been.

"That's pretty much all I can say, though. The Knicks, they were definitely a priority at one point, yes," added Walker, who eventually signed with the Celtics.
