Jayson Tatum and Finals MVP Jaylen Brown close out Dallas in Game 5 to secure Boston's NBA-record 18th championship.

According to Pincus, Kornet will leave Boston behind to sign with the team that won the NBA championship in the season before the Celtics won their record 18th banner — the Denver Nuggets.

His clutch plays on both sides of the ball helped the Celtics secure Banner 18 with the NBA championship. Tatum sent a farewell message to Holiday with a story post via Instagram.
