I'm not a Lebron fan, but I don't really see any anti-Lebron sentiment in Bosh's comments. Basically he is just venting at how frustrating it can be to have to sacrifice parts of your game for the good of the team, which is normal, especially when you are younger.
It was much easier for Pierce, KG, and Ray to do it because they were all past their peaks when they joined up and had already built their individual legacies.
I don't agree. Yes, Pierce, KG, and Ray were all at, or near the end of, their respective primes, but the reasons why they played so well together was 1). because of Garnett. His team-first, self-sacrificing attitude and play made passing contagious among our guys, and 2). and this might be the most important factor as to why our guys really clicked - their styles of play complemented each other so well. We had a slasher in Pierce, a shooter in Ray, and a dominant post-player in Garnett. Additionally, they were all excellent passers and unselfish players, but, more importantly, especially when you compare them to Miami's trio, they were all GREAT SHOOTERS. From any range. Pierce still has the best midrange game in the league and is also an excellent 3-point shooter, so you couldn't help off of him, let alone Ray Allen, and Garnett, when he first arrived, I was concerned that he took so many midrange shots instead of posting up, but my god, did he ever miss one lol? That's the difference. Miami's 3 never complimented each other, and you could make the argument that Bosh was the best shooter of the group. He was also the only one who could play without the ball, while Wade and Lebron practically took turns on each possession because they couldn't do anything else. Why else did the Heat assemble so many shooters on their team? Wade used to be a good midrange player, but he was never on Pierce's level, and only last year did Lebron's jumper look greatly improved from any distance. Still, if one of them had the ball, it was easy to double team the other guy because that guy who was left uncovered (whether it was Lebron or Wade) didn't have the range, ability, or, especially, the consistency to make the defense pay for helping off of him. They did improve at moving off the ball, particularly in their last 2 years together, but I just never got the sense that their respective styles of play ever clicked like it did for our guys.
