Mandatory Credit: Brad Penner-Imagn Images The Boston Celtics reportedly agreed on a three-year, $47.4 million deal with center Mitchell Robinson, who was part of the champion New York Knicks this past season.
A defensive force, Robinson averaged 7.5 points, 8.0 rebounds and 1.7 blocked shots in 397 games (215 starts) with the Nicks since entering the league in 2018. He has topped 100 blocks four times while totaling 690.
Last season, Robinson averaged 5.7 points, 8.8 rebounds and 1.2 blocked shots in 60 games (16 starts). He rejected 70 shots while averaging 19.6 minutes per game.
In the postseason, Robinson averaged 4.8 points and 5.5 rebounds in 18 contests while playing 13.9 minutes per game. The 28-year-old played through a broken right pinkie as the Knicks beat the San Antonio Spurs in five games in the NBA Finals.
The Celtics also reportedly reached a one-year deal with point guard Mike Conley, who will be entering his 20th NBA season.
Conley, 38, averaged career lows of 4.5 points and 2.9 assists in 54 games (15 starts) for the Minnesota Timberwolves last season.
Conley once was a top-tier player for the Memphis Grizzlies. He played 12 seasons with the Grizzlies before spending 3 1/2 seasons with the Utah Jazz and 3 1/2 seasons with the Timberwolves. He was selected to the All-Star Game in 2021 with the Jazz.
A four-time winner of the NBA's Sportsmanship Award and two-time Teammate of the Year, Conley will become only the 14th player in NBA history to reach 20 seasons.
Conley has career averages of 13.6 points, 5.5 assists and 2.9 rebounds in 1,226 games (1,143 starts). His 6,782 assists rank fifth among active players and he stands 14 short of having 2,000 career 3-pointers.
