Except that he had the most points for his team despite that, and had the 4th highest ppg of any nba finals mvp. I'm not a Lebron fan by any means but I can see how much of a player he is. He needs some help like every other player in any team sport.
Did you know how many records he broke during this finals series? http://www.si.com/nba/2015/06/16/lebron-james-finals-mvp-cavaliers-warriors-stephen-curry-andre-iguodala
Read more about what he did by himself during this finals. He could only do so much. It's still a team game and he did what most could not do. To say attempt to diminish what he did because they did not win it all is being simple-minded.
Dude was 65% of their offense, the best EVER in history. What more did you expect him to do? The closest was Jordan at 56%.
