One of the problems with today's 24-hour-coverage-media-marketing-age is that some players are annointed based on looks, potential, a smooth jump-shot, or a large fanbase, while others fail to receive recognition year after year with results such as playoff wins and championship rings.
Lebron James has unique abilities I won't argue that, but he also has huge holes in his game. He's got a streaky jump shot, he's a below average free throw shooter (career %72 ) , he doesn't fight for offensive rebounds and for a guy who's supposedly got the passing game of Magic Johnson his assist to turnover rating is similar to Delonte West's at about 2 to 1. By the way, have I mentioned he's 6'8 and has one season (out of 5) where he's averaged more than one blocked shot per game?
These things go unnoticed year after year because he makes enough "Wow" plays and scores enough points that he's more marketable than say a James Posey - who changes his game on a nightly basis for his team. One night Posey is a defensive stopper, the next night he's a three point specialist, sometimes he's guarding a shooting guard, sometimes he's playing at power forward, the ONLY thing that really wow's you about the guy is how gosh darn good he is at whatever he's focusing on that specific night.
So here's my point: If you watched nothing but ESPN or read nothing but the major sports writers you'd be absolutely shocked to learn that Posey has won championships on three diferent teams (being absolutely integral) while Lebron has never won an NBA championship. The supposition I guess is "It's just a matter of time for Lebron" while the same supposition was made for Allen Iverson and Charles Barkley. I think it's crucial to remember why they play this 82 game season with endless playoffs... For championships. That's the ultimate goal in a game that is all about goals.
So while Lebron get's all the publicity to say whatever he wants, he really hasn't earned the right to say it. The difference with a guy like James Posey is that he HAS earned the right to talk, but he won't. He doesn't have time because right now he's too focused on winning another championship.
