Celtics back home with chance to close out Mavs and clinch record 18th NBA championship​

The Boston Celtics' catastrophic performance in Game 4 of the NBA Finals gave them a chance to clinch another championship on Monday night under the 17 banners already hanging in the TD Garden rafters. “We don't like to lose,” Celtics guard Jaylen Brown said before practice on Sunday. The Celtics cruised through the regular season with the best record in the NBA and then did even better in the playoffs, never trailing in a series while winning 15 of their first 17 games.
