I applaud the troll attempts in your last 2 posts. 10/10
Lebron went to Miami to play with some guys who were actually all-stars (Wade and Bosh). Up to that point, the best players he had played with were Mo Williams and Zydrunas Ilgauskas. Miami was a good team with Lebron and Wade, but certainly nothing like the Warriors.
Mario Chalmers was the main point guard for most of Lebron's time in Miami. Udonis Haslem was the best big man option. The only player to ever have a PPG average in double digits besides the big 3 was 37 year old Ray Allen.
That team did have some nice role players and it certainly was a good team, but nobody will ever remember that team as "one of the greatest of all time". I think everyone saying Lebron being responsible for starting the super teams is mainly because of "The Decision" and the ceremony where he said they're going to win 15 straight championships (all of which was stupid).
Lebron left Cleveland after their front office proved that they were not going to get another legit allstar to play with him. Lebron went to a team that finished 7th in the East the year before he arrived to play with one of his good friends.
In comparison, Durant played with Westbrook, Harden, and Serge Ibaka but never won. Durant was up 3-1 in last year's Western Conference finals and went to the team that beat his. He went to a team that had the guy who won the last 2 MVPs, had 3 all stars and the best bench in the NBA, finished 1st in the West, and just set the NBA record for most wins in a season. That would have been the equivalent to Lebron going to Boston at the time.
