8 a.m. ET: History is just 96 minutes away.
No team in NBA history has ever come back from a 3-0 deficit to win a best-of-seven series, but this series suddenly has a different tenor. The Celtics seized the momentum from the Knicks, who won the first three games, by winning Games 4 and 5 behind strong performances by Kevin Garnett and Jason Terry. Now the Knicks seem worried, and for good reason. If the Celtics win at home on Friday, they force a Game 7 in New York with all the pressure on the Knicks.
Celtics coach Doc Rivers has juggled his rotations throughout the series as he has sought the right combination. He may have found some options he likes after Game 5, when Terrence Williams played 17 minutes off the bench and Brandon Bass delivered a gusty effort on both ends of the court.
Join us for updates and analysis from TD Garden during the game, which tips off at 7 p.m. ET.
