It's a bit of a ludicrous standard to hold a player to - I mean, Jordan failed to win a ring in 9 of his 15 seasons. What's his excuse? Duncan failed to get a ring 12 out of 17 years - what's his excuse? Larry Bird failed 10 out of 13 years, he must be full of excuses. Heck, even Russell's gotta have 2 excuses. It's a bit silly to play the "what's the excuse now?" card when other greats aren't held to the same standard.
Those other greats never left a playoff team in a conspiracy to join two other greats to, they hoped, put together a super-team that destroys everyone else in the league.
Let's be clear about something. LeBron is not KG. Cleveland was not a completely hopeless franchise that had a long record of barely being able to even make the playoffs while making one horrible decision after another. They were a regular playoff contender who put decent but not great rosters around LeBron, until his last year there where they might have been able to win a title and LeBron's performance was one of the main reasons they didn't.
LeBron left a good situation for one where he thought the fix was going to be in and he could take a shortcut to winning that no previous great ever did.
Let's turn it around. What if they Heat had just won their 4th straight title? Would anybody be taken seriously if they argued it wasn't that impressive because the Heat were just so much better than everyone else? Hell, no. LeBron would have been elevated to the same level as Jordan or Russell and anyone who disputed it would have been dismissed as a "hater".
I mean, here's LeBron's legacy over the last 5 years.
2010 - Quit in the playoffs against Boston.
2011 - Lost in the Finals to a Dallas team the Heat had no business losing to.
2012 - Beat a young OKC team in the Finals.
2013 - Won another title after the Spurs made one of the all-time chokes in league history.
2014 - Get absolutely destroyed by the Spurs in the Finals.
Is that a legacy most NBA players wish they could have? Sure. Is that the legacy of the best of all time? No.
