That has only happened with Lebron and while he probably does more to lift his teammates than any other player I've seen more comes into play.Wilt Chamberlain. The NBA had to change several rules due to his dominance. Futhermore, he played at a time when there was better talent top to bottom. Nowadays one man leaves a team, that team goes from one of the best to one of the worst while the destination team goes from the worst to the Finals every year. A real joke of a league.
It is sort of amazing how the people who measure players on championships dismiss Lebron's move to Miami. They think there is some purity in winning with who you were drafted with but what if you were drafted into a franchise whose front office is broken. People want to compare Jordan to Lebron but not consider the front offices they had to deal with.
In the time that Lebron was in Cleveland the only move they made that benefited the team was taking him in the draft and it was the easiest move in history. The Cavs roster was full of replacement level players. A mix of never gonna be young guys and never gonna be again old guys. When he left he didn't have a good enough supporting cast and the Cavs made a horrible move that meant he wouldn't have a good enough supporting cast for the next three years. They traded Zydrinus Ilgauskus for Antawn Jameson and his giant contract. This was before the NBA added the amnesty clause. There was no way Lebron was going to win in Cleveland. Your front office is necessary to win championships and if you don't get drafted into the right one it isn't going to happen. So why do people hate on the player who had the equivalent luck of being born of crackhead parents and having the good sense of leaving? The Knicks aren't going to put you in a situation to win. If Curry had been drafted by the Knicks he never becomes an MVP. He probably gets his soul crushed by all the losing and doesn't do the work he needed to do be as good as he has become. So Lebron leverages his position to put winning first and people hate on him? Idiots.
