The win was especially sweet for LeBron James, who's been considered the game's greatest player never to win a title. He was vilified 2 years ago when he left Cleveland for sunny Miami in his quest for a title.
The Heat took the series from the Oklahoma City Thunder. James was named MVP.
However, James and the Heat aren't the only big winners. Back in April, one lucky fan sunk a basket from half court at the Staples Center in Los Angeles on a day that happened to be his 21st birthday. What's more, his name is Chance.
Today, 21-year-old Chance Lavitch finally picked up his prize. It was a brand new Jeep Cherokee. It's not an NBA championship, but it's still one great birthday present.
