Lebron has been on one 'super team', the Heat. The Cavs were never even close to a super team, and the Lakers aren't shaping up to be either.
I grew up watching Michael Jordan but I think the game is much more difficult now. It's much faster, and a little more physical. Adding Lebron to any team makes them a finals contender overnight. MJ didn't have much luck once he left Chicago. MJ wasn't as dominant after his prime, Lebron will be dominant long after his because of his size.
The Chris Paul trade was blocked for "basketball reasons" because the NBA temporarily owned New Orleans at the time and didn't want to utterly destroy the value of the franchise before finding a new owner.
Besides, you can apply the same "supporting cast" argument to Lebron. Lebron pioneered the approach to forming super teams to chase championships in the modern NBA. That garbage is now rampant thanks to him. (Remember when David Stern blocked the trade of Chris Paul to the Lakers due to "competition concerns?" Boy that seems laughable now)
(All this aside -- Lebron's a great dude, great role model, etc)
