Four straight? Not possible. The Warriors gave up big lead & lost to the Celtics with a 4th quarter collapse.. Then the Warriors came back & clobbered Boston in game 2. Mathematically, winning the NBA championship in only 4 games can’t be done now for either team. Who wanted a sweep or for the NBA Finals to end so quickly?!? This is going longer than 4 games!
The two teams go back to Boston to play games 3 & 4 & return to Golden State for Game 5. It’s possible one of the teams could end the Finals upon the return to Golden State depending if one team sweeps those two games in Boston. If not, the series goes from a 5 games series to a 6 or possible full 7 game championship series. Go Warriors!!!
