The Cleveland Cavaliers and the Boston Celtics, two teams already primed to contend for supremacy in the N.B.A.’s Eastern Conference next season, agreed on Tuesday to one of the biggest deals of a frantic off-season when they swapped All-Star point guards.
The Cavaliers sent Kyrie Irving, one of the most dynamic playmakers in the league, to the Celtics in exchange for a hefty package headlined by Isaiah Thomas, a two-time All-Star. In exchange for Irving, Boston also agreed to send forward Jae Crowder, center Ante Zizic and a 2018 first-round draft pick to Cleveland.
