Never thought I'd say it, but you've got to put LeBron right beside Jordan as the greatest of all time (Bill Russell notwithstanding, don't see how you can compare the eras).
Jordan might be 6 for 6 in the Finals, but he never had to carry such a weak supporting cast on his shoulders alone,* and he was usually on the bench by the fourth quarter resting, not putting up the minutes that LBJ is night after night.
*Except for the two 37-45 seasons with the Wizards that everyone pretends never happened, where he twice failed to make the playoffs with a talented young nucleus.
The 1994 Bulls racked up 55 wins after Jordan retired the first time, and 30 wins in 1999 (lockout adjusted) after they lost Jordan, Pippen, and Rodman.
Could this Cavs team win 20 games in the East without Lebron? I don't know.
LBJ single-handedly kept the Cavs in the lead for most of Game 1, on the road, against the most offensively stacked team in NBA history (this gem aside:

The guy has never got the calls from the ref that Jordan did, never had Phil Jackson or equilvalent leading the team (though Spoelstra remains super underrated), and is playing in a much different, much more demanding era (Jordan broke down in his 15th season, Lebron seems to be getting even better in his).
When he heads out west to join the Lakers with Kawhi and/or Paul George and wins another title, he'll seal the deal as GOAT.
