The Boston Celtics had their first chance to closeout the Dallas Mavericks in Game 4 of the NBA Finals.
They failed miserably.
The Mavericks fended off a sweep by dismantling the Celtics on Friday night at American Airlines Center and handed them the third-largest loss in Finals history with a 122-84 defeat.
It had to be a stinging loss, but Jayson Tatum provided the silver lining for the Celtics.
