Timeline of the National Basketball Association during the 1970s. The timeline includes milestone moments in the league's history and key moments off the court as the NBA celebrates its 75th season:

April 29, 1970: Jerry West forces overtime in Game 3 of the NBA Finals, knocking down a 60-footer that ties the game for the Lakers in Los Angeles at 102. Dave DeBusschere was under the basket as the ball through the hoop, a shot that taken after the creation of the 3-point line would have won the game for the Lakers. Instead, the Knicks won 111-108 in overtime to take a 2-1 lead.

May 4, 1970: Four students are killed and nine wounded at Kent State by National Guard troops during a protest against expanding the Vietnam War and the presence of guard troops on campus.

May 8, 1970: The Willis Reed Game. The captain of the New York Knicks appeared to be sidelined by a badly bruised right hip that kept him out of Game 6, a win by the Lakers that forced a seventh game. The NBA MVP limped onto the court at Madison Square Garden, outjumped Wilt Chamberlain for the opening tip and scored the first basket from the top of the key. Reed hit another jumper but didn't score again in 27 minutes. He had done enough as the Knicks clinched the title with a 113-99 win in Game 7.

March 1, 1971: Spencer Haywood wins a stay from the Supreme Court allowing him to play in the NBA less than four years after graduating high school. He had played a season in the ABA and 21 games into the 1970-71 season for the Seattle SuperSonics when the ruling came down. The NBA and Haywood's attorney settled out of court with the hardship rule allowing players to skip college straight to the league out of high school.

The price of oil per barrel goes from approximately $3 to nearly $12, leading to gas lines as the price per gallon nearly doubled and President Nixon asked gas stations not to sell gas on Saturday nights or Sundays. A national speed limit of 55 was instituted.
