Lol man, this ain't even true... Didn't hear Cavs/LBJ fans last season complaining he was doing it all by himself. It was Kyrie who scored that winner 3, plus Love and JR were on fire as well 
It's all about consistency, gotta give credit to Kyrie's last performance and JR's +20 pts game but it doesn't work if you just disappear 90 percent of the series and just put up a 20 point game. Compare Deron Williams, who was acquired just for this level to Shaun Livingston. He averaged 6.6 pts per game while Deron scored only 5 points in entire series. This is just one example, but can give examples like that. And one last thing, take a look at Cavs' +/- while LeBron is on/off the court, that'll explain pretty much everything I'd mean with that picture.
