That stay-in-the-moment mindset has served them well all season and becomes even more important following a Game 6 loss Friday night, a game in which the Celtics did a lot of what they were intending to do in order to give themselves a shot at winning.
The Cavaliers are 4-2 all-time in Game 7s - including their home victory over in in the First Round.
The difference, of course, is this is 100 games in a row for James.
James looked rattled midway through the fourth quarter when he clashed with teammate Nance Jr, who collided with James' knee. James averages the most points of any player in league history who has played at least three elimination games, ahead of Michael Jordan at 31.3 and Wilt Chamberlain at 31.1.
In 2014, he had 45 points, 15 rebounds and five assists in Game 6 for Miami, which went on to win Game 7 and the National Basketball Association title. If they manage to get an advantage in every spot except for James, which we have seen twice before in this series, the Celtics can get the win that puts them in the Finals.
"The best player in the game", said Stevens. He was helped off and walked to the bench unsteadily before heading to the locker room for further treatment and evaluation. "Either you're being very kind because it's National Wine Day, or I love Brazil, or I don't know what it is right now". "That's no excuse, so we're looking forward to it". Plus, while James remains a marquee draw, as do the Warriors, another meeting between them this year would make four straight Warriors-Cavs Finals.More news: 'US can't decide for the world:' Rouhani rejects Pompeo's Iran demands

Following the incident, he scored 12 points, including back-to-back three pointers to seal Cleveland's victory.
"It's not going to be pretty", Celtics guard Marcus Smart said.
"The 6'10", 250-pounder averaged 17.9 points and 9.3 rebounds on the season, and has been Cleveland's second-leading scorer in the regular season and playoffs. In Games 3, 4 and 6, the Celtics went 0-3 and were outscored by 49 points.
"It's been better, but I'll be ready tonight", James said at shootaround when asked for an update.
The Celtics have already played a Game 7 in this postseason, handily beating Giannis Antetokounmpo and the Milwaukee Bucks in the first round.
Lue said he wasn't concerned about James' leg. The C's improved on Friday night shooting over 50% from the field but still missed open shots.
