With LeBron James' announced decision now part of NBA folklore, Miami has for now become the capital of the NBA universe.

With a Tweet from Newsday's Alan Hahn shortly after midnight on Thursday, July 8th, news surfaced that LeBron had decided to join Dwyane Wade and Chris Bosh with the Miami Heat.

We have seen big three's come in various forms and qualities over the years, but it is not hyperbole to claim we have never seen a big three this BIG.

Even though he still needs to improve his jumper and post game, LeBron is easily the best player in the NBA.

An argument can be made for Wade being the second best player and I don't know of anyone who makes a living playing or covering the NBA who would put him outside of the top-5.

Meanwhile, Bosh is firmly in the top-15 and also has the added value of being a big.

Since the Heat are almost entirely stripped, with only Michael Beasley and Mario Chalmers under contract and now likely gone, the type of supporting cast that is built around this Three-Dream Team will instantly become the biggest determinant on how quickly they manage to win a title.

There is no 'if' clause in the preceding paragraph because if this trio fails to win a title, it would be a colossal failure and a visceral shock of equal proportions.

The initial reaction, a perfectly normal reaction, is to discredit their chances in Year 1 due to the supporting cast. But the counterargument is that there is no precedent for this special of a union.

The tried and true formula for winning titles is to have one legitimate MVP candidate and a solid perennial All-Star, followed by a decent collection of role players who fill specific needs.

Well, the Heat will have the two best players on the floor every single night of the year, with maybe a few exceptions if we're being generous to Kobe Bryant and Kevin Durant. Bosh will be, at worst, the fourth best player on the floor on most nights.

The list of free agents is uniquely long and they will be able to sign a warm body to start at point guard and center that we have at least heard of, even if they are past their prime. The obvious needs for the Heat will be spot-up shooters, a true big who can take up space and players that can defend. It is the general formula that worked for Cleveland during the regular season and easily carries over to this incarnation.

It won't be easy, but ring chasers will be flocking to be a part of this situation and these three players may take less cash to allow a little more to go around.

Assuming they do reach the Finals in Year 1, which I think is a safe assumption, how they will defend the interior against Pau Gasol and Andrew Bynum will be the toughest vulnerability to cover.

The gutted team strategy from the Heat was obviously risky, but it was deemed a success once they were able to retain Wade and land Bosh on Wednesday morning and now getting LeBron goes beyond even their most wild and ambitious dreams.

There really isn't much I'm interested in doing in regards to numbers at this point, because conceptually the very notion of these three playing together says more than enough. I can link to a piece I wrote in early June about the Biggest Big 3s, which included adding up their PER from 09-10. The number was 84.4 (LeBron: 31.2, Wade: 28.1, Bosh: 25.1), which utterly aniliates any Big 3 we have ever seen, with most title winners having a Big 3 in the mid to high 60s.

Obviously, those PERs will decrease in 10-11 substantially because their usage will go from astronomical in their previous situations to this one where they must all share the ball.

Grade for Heat: A+

Continuing the numbers theme briefly, it is hard to see a situation where LeBron's number sustain as they historically were in Cleveland over the past few seasons. But if he ever was destined to average a triple double, doesn't it have to come during the 10-11 season?

Though he reached 8.6 per game in 09-10, the assist number was always going to be the toughest one for him to get into double-digits and now he'll have Wade and Bosh finishing those brilliant passes we've come to expect from him. He also will need to carry more weight on the glass until the Heat are able to acquire some Anderson Varejao types.

The essential nature of his legacy is now permanently altered and very possibly will be minimized. He has left his home state of Ohio without delivering their first title since the 1960s and he has chosen to do business in a city that is far from passionate about sports and also with two of the best players in the game.

The only explanation I can think of that led LeBron to choose Miami is how mortal he felt in the way Cleveland lost to the Celtics in Game 5 at home and in Game 6 in Boston to be eliminated in the Eastern Conference Semifinals. He will turn 26 at the end of 2010 and the clock has begun to tick a little louder on the amount of prime seasons he has remaining.

Even if the Heat win four or five titles, LeBron's legacy is unlikely to be as celebrated as it would be for even one title in either Cleveland or New York. He also runs the risk of being the Alex Rodriguez to Dwyane Wade's Derek Jeter.

If he wanted an easier path to a title than what Cleveland, New York or New Jersey were offering, he could have picked the Bulls without sacrificing any genuine aspects of what his legacy was capable of looking like.

Grade for LeBron: C+
