Celtics to sign championship-winning forward

Boston opened up a frontcourt spot for Boucher by agreeing to trade Georges Niang to Utah on Tuesday. Boucher will compete for minutes at both the power forward and center spots for the Celtics, who have been busy shedding salary and revamping their roster throughout the offseason.

Save for one cameo appearance with Golden State in 2017-18, Boucher has spent his entire career with the Raptors. Boucher has been a key reserve for Toronto the past seven seasons, appearing in 406 games but only 23 starts. He’s averaged 8.9 points and 5.1 rebounds in 17.7 minutes during his NBA career while shooting 48.8 percent overall and 33.9 percent beyond the three-point arc.

Boucher, 32, saw action in 50 games last season, averaging 10 points and 4.5 rebounds in 17.2 minutes. He didn’t appear in a game after Feb. 26 as the Raptors decided to essentially shut down the veteran big man and take a long look at their younger players.

Boucher was the last remaining player from the Raptors’ 2019 championship club. He holds the all-time franchise records as a reserve for points, rebounds, blocks, minutes and games played.

Toronto held Boucher’s Bird rights and reportedly was interested in re-signing him, but that didn’t come to fruition. He’ll now join another Atlantic Division club.
