Well, look at what Pat Riley did to the Heat compared to SVG. He got players like Jason Williams, Antoine Walker, Alonzo Mourning, and James Posey to put their egos aside and play as a team and because of that,, the Heat are 4 wins away from a Championship trophy.
Phil Jackson was able to get Kobe and Shaq to put aside their differences, but that only worked for 4 seasons. After ending their Championship run against the Spurs, they were back at it. All because Shaq suggested that Kobe would pass more until he heals from his injury that he had, and then Kobe went apesh!t.
