The Boston Celtics have exercised the contract options for Terry Rozier’s third year and Marcus Smart’s fourth year. 

Rozier, a 6’2” guard, has appeared in all three games for the Celtics during the 2016-17 season and has posted averages of 6.0 points, 3.3 rebounds, 3.0 assists and 1.33 steals in 23.9 minutes per game. He posted a career-high of eight points to go along with four rebounds and four assists against Chicago on October 27, 2016. During his rookie season last year, Rozier appeared in 39 games for the Celtics and totaled 72 points, 63 rebounds and 37 assists in 311 minutes. He increased his production during the 2016 preseason when he averaged 9.6 points, 2.1 rebounds and 2.3 assists in 17.2 minutes per game while shooting 54.0 percent from the field and 60.0 percent from three.

Smart, a 6’4” guard, has posted career averages of 8.4 points, 3.7 rebounds, 3.1 assists and 1.5 steals in 128 career games since the Celtics drafted him 6th overall out of Oklahoma State in the 2014 NBA Draft. During the 2015-16 season, Smart posted career-highs in points (9.1 per game) and rebounds (4.2 per game) while being selected to participate in the 2016 Rising Stars Challenge during All-Star weekend.

James Young has won the final spot on the Boston Celtics' regular season roster.

Boston will have to waive R.J. Hunter, who they were unable to unload for a future second round pick.

Hunter was the 28th overall pick out of Georgia State in the 2015 NBA Draft.

The Boston Celtics have signed forward Ryan Kelly. 

Kelly, a 6’11” forward, appeared in six games for the Atlanta Hawks during the 2016 Preseason where he averaged 4.8 points, 2.7 rebounds and 1.3 assists in 15.0 minutes per game. Originally drafted by the Los Angeles Lakers with the 48th overall pick in the 2013 NBA Draft, Kelly has appeared in 147 career games and recorded averages of 6.5 points, 3.3 rebounds and 1.4 assists per game.

Kelly appeared in seven games (all starts) during the 2015-16 season for the Los Angeles D-Fenders of the NBA Development League while on assignment from the Lakers and averaged 27.0 points, 7.3 rebounds, 3.0 assists while shooting 52.9 percent from the field and 37.5 percent from three.

Marcus Smart suffered a left ankle sprain in Wednesday's preseason game and will be out for multiple weeks.

It is the same ankle that Smart has sprained before, but it doesn’t appear to be as bad a previous ankle sprain.

Smart was helped to the locker room by teammates as he didn't put any weight on the ankle.

The Boston Celtics and Chicago Bulls held discussions at the draft centered on Jimmy Butler.

According to the Chicago Tribune, one of the proposals was Jae Crowder, the No. 3 pick and the No. 16 pick. The Bulls would have used the pick on Kris Dunn.

A source says the Bulls also demanded an additional starter-level player in the trade.

Butler was an All-Star in 2015 and 2016 but the Celtics felt the price was exorbitant. 

While the Boston Celtics are setup to possibly make multiple blockbuster trades as they did in 2007 when they acquired both Kevin Garnett and Ray Allen in a single postseason, Danny Ainge won't rush into a move and won't necessarily ever make one of their magnitude.

The Celtics were linked to a trade for Jimmy Butler at the draft and also reportedly had interest in Russell Westbrook.

“When you make mistakes is when you say you have to do something,” Ainge said. “There’s a lot of names out there that we’ve talked with about trying to acquire, but we wouldn’t pay the price. We’re prepared to build on what we have if that’s the best path.”

Boston has made two excellent smaller trades in acquiring Isaiah Thomas and Jae Crowder.

“We’re trying to find deals. And sometimes you have to make small deals in order to be able to have big deals,” Ainge said. “You have to put yourself in position with good young players and good contracts and future assets. It puts us in the game if there’s a player that becomes available in the trade market, but they have to like those young players and assets,” he continued. “In the meantime, we’re not sitting around and waiting for something like that to happen. We’re trying to make something like that happen, but we’re not just chasing every player out there.”

The Boston Celtics continue to have real interest in Gordon Hayward.

Hayward will be an unrestricted free agent in the offseason and the Celtics will have a max contract and a chance to reunite with Brad Stevens to offer him.

Hayward signed a four-year, $63 million offer sheet with Charlotte in 2014 that was matched by the Utah Jazz.

Hayward has been one of the NBA's best wings to not make an All-Star Game.

The Boston Celtics have interest in signing J.R. Smith, who remains in a contract stalemate with the Cleveland Cavaliers.

Smith is seeking $15 million per season from the Cavaliers while they are only offering $10 million or $11 million annually.

The Celtics would have to clear substantial cap space to sign Smith to a competitive deal.

Boston has Avery Bradley as their starting shooting guard.

The report also indicates there are several other teams with interest in Smith.
