Now, the series goes to a Game 7, or as James calls it, "the best two words in sports", in Boston.
As we've seen all series long, the Cleveland Cavaliers were a different team at home compared to the miserable wreck they've been on the road in Boston.
However, now that the end of the season is near, it's even more pertinent to brood on what a Cleveland loss prior to making the NBA Finals would mean for LeBron's future.
Starting guard J.R. Smith made only three of 22 shots in the three games in Boston for a total of six points.
James also passed Karl Malone for sixth place all-time in playoff rebounds. "Championship pedigree, giving it his all". James is one of the most remarkable runs in the history of the National Basketball Association with his Finals streak, but this is the most vulnerable he has looked since the last time the Celtics beat the Cleveland Cavaliers. He played the game's first 35 minutes before resting, expending enormous energy to keep the Cavs alive.
He departed the game with less than a minute remaining to a frenzied ovation.
LeBron James spent most of Friday night's Game 6 matchup doing what LeBron James does all the time it seems - dominate games. The last team to represent the East in the Finals that didn't have James - the Celtics in 2010.

The Cavaliers appeared doomed when Love clashed heads with Boston rookie Jayson Tatum in the first six minutes and went back to the locker room and didn't return.
- The Cavaliers turned the A/C in the building up on a hot late-May afternoon.
James was writhing in pain on the floor, but eventually got up and finished the game.
After a few moments he rose gingerly and continued. "But, no, he just fought through everything tonight".
"It's going to be a lot of fun, first and foremost", said Terry Rozier, who scored a team-high 28 points on 10-of-16 shooting.
Celtics players were disappointed in a sloppy second-quarter effort that left them playing catch-up after a solid start.
"We just can't expect coming home and in front of our great fans and crowd that we're going to win the game", Lue said.
The victor will meet Houston Rockets or Golden State Warriors.
