MIAMI - LeBron James could not sleep after Game 6.
Imagine, then, how frayed his emotions will be going into Game 7.
So much is at stake. Legacies, for so many players, James included. The NBA championship. Whether the season was a success or a bust. How he will be portrayed over the next few months. How history will judge a Miami Heat team that won 27 straight games in one stretch, 66 games in the regular season and now 81 games overall.
Although the Heat will insist otherwise, the common belief is that it all hinges on James' shoulders. And the four-time NBA MVP wouldn't have it any other way when his Heat take on the San Antonio Spurs in Game 7 of the NBA Finals.
"I want to go down as one of the greatest. I want our team to go down as one of the greatest teams. And we have an opportunity to do that," James said. "Hasn't been many teams to win back-to-back championships. It's so hard. It's the hardest thing. I said last year it was the hardest thing I've ever done, winning my first. Last year don't even come close to what we've gone through in this postseason and in these Finals."
James was so weary afterward that he had trouble pulling himself up from the chair where he conducted postgame interviews.
"First of all, I'm blessed, man. I don't even know how I got here," he said. "I wasn't supposed to be in the NBA, if you go by statistics and things of me growing up where I grew up. Every time I go into my locker room and see the 'James' on the back of an NBA jersey, I'm like, 'Wow.' No criticism can deter me from playing this game because of that. I'm not supposed to be here."
He means that in a more broad sense, but in simplest terms, that also applies to Thursday night.
The Heat probably aren't supposed to be there. They were down by five points with less than a half-minute to go in regulation of Game 6. The championship celebration was being readied, literally around them. The Spurs were about to get their hands on the Larry O'Brien Trophy, and the Heat were about to slink off into another offseason of utter disappointment.
Until, of course, none of that happened.
James made a 3-pointer to get Miami within two, and after the Spurs gave Miami life by missing a free throw, Ray Allen sent it to overtime with another 3-pointer. In the extra session, James and the Heat found a way to pull out a 103-100 win, one that left Miami exhausted and San Antonio devastated. They collide one last time on Thursday with all eyes on James, who struggled for much of the game and still finished with 32 points, 10 rebounds and 11 assists.
"He had an 'off' triple-double," Heat guard Mike Miller said. "I can't have an 'on' triple-double."
In James' lifetime, only four franchises - Chicago, the Los Angeles Lakers, Detroit and Houston - have won consecutive championships.
If Miami pulls this off, a second straight Finals MVP award will likely be his, to go with the four regular-season MVPs. He'll be a two-time champion, to go along with his two Olympic gold medals. Others have won more titles and more MVPs, but poking holes in James' resume will become a considerably tougher task, even for his biggest naysayers.
"We can't worry about what the history books say. That's why it's history," James said. "We have to live in the present. We have to live in the moment. And we have to do whatever it takes to bring that trophy - or to keep that trophy - here in Miami."
