Cleveland team-mate Matthew Dellavedova tried to sum up James' performance against the Golden State Warriors earlier in June, after the four-time MVP almost singlehandedly delivered the Cavs their first championship.
Trailing 3-1 in the best-of-seven series, James posted back-to-back games of 41 points to level the matchup before his triple-double of 27 points, 11 assists and 11 rebounds completed the remarkable comeback in Golden State in game seven.
"Being 3-1 down with two games on the road to play and he plays some of the best basketball of his career," Dellavedova told Omnisport.
"It was unbelievable what he did. I can't imagine how much pressure he was feeling. Not only because he is the best player on our team and he is our leader, and he came back to Cleveland.
"The weight of the team was on his shoulders and he delivered."
The 93-89 win in Golden State on June 19 sparked wild scenes back home in Cleveland as the city and Cavs fans finally celebrated an NBA title.
Australian point guard Dellavedova, who is set to become a free agent on Friday, added: "It's hard to put it into words. It will take a while to sink in.
"The adrenalin was pumping. I think it's still going because the week after just trying to sleep, there wasn't much sleep."
