 an NBA record with their 18th championship title. Boston will be visiting the Dallas Mavericks for Game 4 of the NBA Finals, and that is tonight. The Celtics with a 3-0 lead in the series, and they're in pretty good shape with a chance to sweep it and win it tonight. Yeah, it's going to be a tough battle, I think. Dallas isn't going to want to go down in a sweep, but we'll see what happens. There's so much depth with the Celtics this year.
