The thing with the Heat is, Lebron is so dominant as a player that no matter who he plays with it'll always look like "He needs more help."
He's so ball dominant, he can literally do it all on offense, that it would be ridiculous to not play through him. This is where Barkley , and the rest of the world look and say "Lebron needs more help" when in actuality he doesn't. It just appears that way because he can, and does do everything. The fact that he has players like D Wade and Bosh only needing to chip in marginally (By Marginally I mean relative to their talents) speaks volumes about just how good Miami is.
