MIAMI — The decision is final: LeBron James made the right call coming to Miami.

Finally an NBA champion, it's all worth it now.

James had 26 points, 11 rebounds and 13 assists, and got the kind of help that was worth leaving home for, leading the Heat   in a 121-106 rout of the Oklahoma City Thunder on Thursday night to win the NBA Finals in five games.

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

James has found it all since taking his talents to South Beach.

"It means everything," James said moments after the win. "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."

He 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 celebration 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 watched the confetti rain   down from the rafters.

The Heat took control in the second quarter, briefly lost it and blew it open again in the third behind their role players,   James content to pass to wide-open 3-point shooters while the Thunder focused all their attention on him.

Bosh and Wade, the other members of the Big Three who sat alongside James as he promised titles at his Miami welcoming party   two summers ago, both had strong games. Bosh, who broke down in tears as the Heat left their own court after losing Game 6   last year, finished with 24 points and Wade scored 20. The Heat also got a huge boost from Mike Miller, who made seven 3-pointers   and scored 23 points.

The disappointment of losing to Dallas in six games last year vanished in a blowout of the demoralized Thunder, who got 32   points and 11 rebounds from Durant.

That made it easier for James, the most heavily scrutinized player in the league since his departure from Cleveland, when   he announced he was "taking his talents to South Beach" on a TV special called "The Decision" that was criticized everywhere   from talk shows and water coolers straight to the commissioner's office. James has said he wishes he handled things differently,   but few who watched the Cavaliers fail to assemble championship talent around him could have argued with his desire to depart.

He found in Miami a team where he never had to do it alone — though he reminded everyone during his sensational postseason   run that he still could when necessary. He got support whenever he needed it in this series, from Shane Battier's 17 points   in Game 2 to Mario Chalmers' 25 in Game 4.

In the clincher it was Miller, banged-up from so many recent injuries that he practically limps from the bench to scorer's   table when he checks in. He made his fourth 3-pointer of the half right before James' fast-break basket capped a 15-2 run   that extended Miami's lead to 53-36 with 4:42 remaining in the first half. James had 15 points, five rebounds and five assists   at halftime, with the Heat ahead 59-49.

Durant added 11 rebounds for the Thunder, who made a remarkably early trip to the NBA Finals just three years after starting   3-29. With Durant, Russell Westbrook, Serge Ibaka and James Harden all 23 or younger, the Thunder have the pieces in place   for a lengthy stay atop the Western Conference.

But their inexperience showed in this series, a few questionable decisions, possessions and outright mistakes costing them   in their franchise's first playoff appearance since Seattle lost to Chicago in 1996. Westbrook scored 19 but shot only 4 of   20, unable to come up with anything close to his 43-point outing in Game 4, and Harden finished a miserable series with 19.

Nothing they done could have stopped James, anyway.

Appearing fully over the cramps that forced him to sit out the end of Game 4, he was back to his dominant self, a combination   of strength and speed that is practically unmatched in the game — and rarely seen in the history of it.

Wade skipped to each side of the court before the opening tip with arms up to pump up the fans, then James showed them nothing   wrong with his legs, throwing down an emphatic fast-break dunk to open the scoring. He made consecutive baskets while being   fouled, showing no expression after the second, as if he'd hardly even known he was hit. Drawing so much attention from the   Thunder, he started finding his wide-open shooters, and the Heat built a nine-point lead before going to the second up 31-26.

Oklahoma City got back within five early in the third before consecutive 3-pointers by Chalmers and Battier triggered a 27-7   burst that made it 88-63 on another 3-pointer by Miller. James didn't even score in the run until it was almost over, hitting   a pair of free throws after he was flagrantly fouled by Derek Fisher while powering toward the basket.

Gone was the tentative player who was mocked for shrinking on the big stage last year, too willing to defer to others who   didn't possess half his talents. This time, he was at peace off the court and on attack on it, vowing to have no regrets and   playing in such a way they wouldn't be necessary.

James promised multiple titles at his welcoming party, and the Heat have three pieces to build around. Pat Riley will have   to fill some holes on the roster, but will likely find some players eager to come to Miami for the good weather and great   chance to win.

Miller was one of them last year, and though injuries have ruined his effectiveness, his shooting turned this into the only   blowout of the series after Miami had outscored Oklahoma City by just 389-384 over the first four games.
