Best player in the game. Best team in the league.

Now NBA champion, too.

LeBron James is finally savoring it all since taking his talents to South Beach.

''Happiest day of my life,'' he said.

James had 26 points, 11 rebounds and 13 assists, leading the Heat in a 121-106 rout of the Oklahoma City Thunder on Thursday night to win the NBA Finals in five games.

All that was left was a celebration nine years in the making - and two years after his acrimonious parting from the Cavaliers.

''It means everything,'' James said moments before being named the playoffs MVP to go along with his regular-season award. ''I made a difficult decision to leave Cleveland but I understood what my future was about ... I knew we had a bright future (in Miami). This is a dream come true for me. This is definitely when it pays off.''

James left the game along with Dwyane Wade and Chris Bosh for good with 3:01 remaining for a round of hugs and the start for a party he's been waiting for since arriving in the NBA out of high school as the No. 1 pick of the 2003 draft. James hopped up and down in the final minutes, shared a long hug with opponent Kevin Durant, and then smiled as he watched the confetti rain down from the rafters.

''It's about damn time. It's about damn time,'' James said.

He was a choker last year, the guy who came up small in the fourth quarter, mocked for ''shrinking'' in the moment while playing with what he called ''hatred'' in trying to prove his critics wrong.

He came to Miami seeking an easier road to the finals but found it tougher than hoped, the Heat coming up empty last year and nearly getting knocked out in the Eastern Conference finals this time by Boston. Facing elimination there, James poured in 45 points on the road to force a Game 7 and the Heat won it at home.
