The Oklahoma City Thunder were established in 1967 as the Seattle Supersonics. Their first stars were Walt Hazzard, Lenny Wilkins, Bob Rule, and Spencer Haywood. With Wilkens' great all-around averages, and Rule's and Haywood's outstanding rebounding and scoring, the team improved steadily, eventually having their first winning season in 1972. The team didn't make the playoffs for the first time until two years later. In 1973, Wilkins was dealt to the Cleveland Cavaliers in an unpopular trade, and the team fell apart, only winning 26 games that season. Bill Russell was then hired as head coach, and led them to their first playoff berth, which happened to be the Western Conference Semifinals, for two years in a row. Russell left in 1977 and they brought in Lenny Wilkins, this time as a coach. The Supersonics posted their best season yet and made it to the NBA Finals for the first time, but ended up losing to the Washington Bullets in a tough 7 game series. The following season was the opposite as the team beat the Bullets in the finals in 5 games for their first and only title so far. The team remained strong, winning 50+ games two times in 4 years. The 80's were a period of slight decline, but the team still had seasons where they won 45+ games, and they also made it to the Western Conference Finals. The 90's was where they really got a jumpstart though. By 1992, the team had star point guard Gary Payton and the powerful foward Shawn Kemp, which would be the foundation of the team's success during this period. The team won 50+ games for 5 years in a row and won 60+ games 3 out of those 5 years. Their most successful year during this period saw the team win an amazing 64 games, and they made the NBA Finals, but they lost to Michael Jordan's Bulls in 6 games. When 2000 would hit, the team would struggle, and the only positive was their 2004-2005 season where they won 52 games. This led the team to move to Oklahoma City in 2009, and are now called the Thunder. The team today is led by stars like Kevin Durant, Russell Westbrook, James Harden, and Serge Ibaka. Their overall record is 1939-1726 (.529). Their best season was their 1995-1996 season where they got a impressive 64-18 (.780) record and their worst season was their 2007-2008 season where they got a 20-62 (.244) record. They've retired 6 numbers and a microphone. 1 (Gus Williams), 10 (Nate McMillan), 19 (Lenny Wilkins), 24 (Spencer Haywood), 32 (Fred Brown), 43 (Jack Sikma), and a microphone for radio announcer Bob Blackburn.
