Not saying the Cavs run a team that well, but that fact that you mentioned that the Cavs made it to the Finals and say the sucked in the same breath is counterintuitive at best. Further, to say that Riley puts his players first is somewhat misleading as well. If anything, the Cavs probably catered to Lebron too much. I'm sure all these player moves didn't go without at least some influence from LeBron. Some teams have the intensional fortitude to tell their stars to worry about playing basketball and let management make player moves. Others organizations have allowed players to dictate moves or have given too much control and it's blown up in their face. Watching the Spurs face the Heat is like watching two polar opposites clash. An organization like the Spurs would not put up with prima donnas and would most likely boot their *** out of San Antonio. While Spurs aren't my favorite team, I probably admire their front office more than any in League.
In regard to the picture with Bird, MJ and Magic. It's clear that they didn't win championships by themselves; however, the overarching theme is none of them abandoned ship. Fact of the matter is LeBron took the path of least resistance. He left because he knew it would be easier with Wade and Bosh plain and simple.
EDIT: sorry, I was trying to quote the person you replied to, but after submitting, I see that it only captured your reply. I'm on my pad and having some technical difficulties, sorry.
