Does it really matter how a team is put together as long as it is done within the rules? Ironically, the only reason the Lakers got Worthy was because of a stupid trade made by the Cavaliers.
Actually, it does to a point. Lebron worked together with 2 other superstars to build his first super team. Then, when he decided that one wasn't working anymore, he left to go build another one. He was completely disingenuous in both situations too.
The Lakers built theirs through drafts and trades. Also, on the Kobe trade demand. Here's another difference. Kobe said, get me some help or trade me. The Lakers chose to get him some help. Lebron, on the other hand, bailed on the Cavs and then the Heat.
In other words, Kobe gave his FO the chance to go out and get him some help and they responded. Lebron didn't give the Cavs or the Heat the same opportunity. He didn't even give them the opportunity to do a sign and trade.
