In just one season, the Oklahoma City Thunder have transformed from an immature club blessed with talent but searching for an identity into a genuine title contender.
The pieces to the puzzle essentially remained the same from a year ago but the youthful Thunder played this season with a swagger, a sense that they belonged in the NBA Finals.
"A lot of guys and a lot of people around the league say we're young and we're not able to make clutch shots, perform under clutch moments, and I think it wills us," said 23-year-old guard Russell Westbrook.
That drive will get tested in the NBA Finals when the Thunder face LeBron James and the Miami Heat, another team with a chip on its shoulder for other reasons.
James and his Miami cohorts are returning to the National Basketball Association (NBA) Finals determined to deliver on their celebrated promise two years ago to produce a passel of titles after the "Big Three" of James, Dwyane Wade and Chris Bosh joined forces in South Beach as free agents.
The heat will be looking to avenge last season's upset to the Dallas Mavericks in the finals and prove they are more than just a glitzy show, the Oklahoma City franchise has not made it this far since 1996 when the club was still in Seattle.
The Seattle SuperSonics won the championship in 1979, the only time in 41 years playing in the Emerald City that they were the National Basketball Association's (NBA) last team standing.
Team owners fought with lawmakers in Seattle and relocated the club to Oklahoma City for the 2008-09 season.
Despite the move, the club retains a distinct Seattle flavor: Four of the team's key players, leading scorer Kevin Durant, Westbrook, shot-blocking specialist Serge Ibaka, and swingman Nick Collison were drafted by the Sonics.
The young Thunder, eager to prove their future is now, make noise with a "Big Three" of their own as Russell Westbrook and James Harden provide plenty of firepower to augment the dynamism of Durant, who at age 23 has won three NBA scoring titles.
The leader of the band unquestionably is Durant, the NBA's three-time leading scorer who, despite being 6-foot-9 (2.06m), plays with the smoothness of a point guard.
"We never just thought that we were supposed to wait our turn," Durant said after the Thunder defeated San Antonio in six games in the Western Conference finals. "We always wanted to go and take everything.
"Coach (Scott Brooks) always emphasizes that every opportunity we step out on that floor is a great opportunity to get better and grow and fight toward our dreams, and we all knew that.
"We've got a long ways to go still. We've just got to take it a day at a time."
To reach the finals, the Thunder bounced the defending champion Mavericks in four straight and then needed just five games to dispatch Kobe Bryant and the Los Angeles Lakers.
Against the Spurs, Oklahoma City lost the first two games before reeling off four straight wins to give the franchise its first appearance in the finals since the Michael Jordan-led Chicago Bulls beat the SuperSonics in six games 16 years ago.
The Thunder have their drawbacks. They do not share the ball very well, a key reason they ranked last in assists this season.
But they are young, athletic, and when the ball is going in the basket, it does not matter if there was an assist. They are not the same unrefined club that lost to the Mavericks last year in the Western Conference finals.
Spurs coach Gregg Popovich is a believer.
"They went through Dallas, last year's NBA champion, then they went through the Lakers, then they went through us," he said. "Those three teams represent 10 of the last 13 championships."
The series should also bring some well-deserved recognition to the head coach of the victorious team.
Heat coach Erik Spoelstra and Thunder pilot Scott Brooks have toiled in the background, but may play a pivotal role in the chess match of how best to use their high-profile players in what promises to be a scintillating best-of-seven showdown.
