BOSTON — Jaylen Brown had an up-and-down postseason. There were the highs: a 36-point explosion with Jayson Tatum sidelined in Game 2 against the Orlando Magic, a 26-point, 12-assist outing to keep the Celtics alive in Game 5 against the New York Knicks.
And, there were the lows: 7 turnovers in the Celtics’ final game, a blowout loss at Madison Square Garden, and 35% shooting across the Celtics’ first two losses, in which the Celtics lost consecutive 20-point second-half leads.
Through it all, it was evident that Brown was playing through knee pain — pain that the Celtics initially termed a right knee impingement but was later reported to be a partial meniscus tear by ESPN’s Ramona Shelbourne.
