The 2009–10 NBA season was the 64th season of the National Basketball Association (NBA). The 1,230-game regular season (82 games for each of the 30 teams) began on Tuesday, October 27, 2009, and ended on Wednesday, April 14, 2010.
The 2009 NBA Draft was held on June 25, 2009, and Blake Griffin was selected first overall by the Los Angeles Clippers.^[1] The Dallas Mavericks hosted the 59th Annual All-Star Game at Cowboys Stadium in Arlington, Texas on February 14, 2010.^[2]
For the second time in NBA history, all eight Western Conference playoff teams won at least 50 games, and only 7 wins separated the Western Conference #1 seed from #8 seed. Both of these events first occurred in 2008.
Cleveland's league-leading 61 wins was the lowest win total to lead the league since the Indiana Pacers won 61 games in 2003–04.^[3]
The New Jersey Nets became just the fifth team in NBA history to lose 70 games in a season. Taken from http://en.wikipedia.org/wiki/2009%E2%80%9310_NBA_season.
