NBA free agents can begin reaching agreements with teams at 6 p.m. ET Sunday. Contracts can be officially signed July 6.
Walker is coming off his best season as a pro during his eight seasons with the Charlotte Hornets, averaging 25.8 points while playing in all 82 regular-season games.
After a season of locker room turmoil often centered around Irving’s discontent, the Celtics crave the stability and leadership that Walker will crave – along with an All-Star talent in the prime of his career.
Walker can plug into a Celtics lineup that includes Jayson Tatum, Gordon Hayward and Jaylen Brown. Boston can still pursue a center with its $4.8 million exception and deliver a team to the start of the season that could be competitive with the elite teams in the Eastern Conference.
Walker won a national championship at nearby UConn in 2011, and is a New York City native.
