History of basketball: 10 quirky facts you probably didn't know about the NBA

#3 2013-14 is the only season the Lakers, Celtics and Knicks all missed the playoffs

The Boston Celtics' Big Three era came to an end with the departure of Ray Allen to the Miami Heat as a free agent in 2012. They held on gamely for another season and made the playoffs once more in 2013, but Danny Ainge had set his sights on rebuilding for the future. He traded aged Jason Terry, Paul Pierce and Kevin Garnett to the Brooklyn Nets in exchange for a motley crew of journeymen and 3 precious draft picks (unprotected) in one of the most lopsided trades of this century.

While the Lakers and the Celtics tanked intentionally in the 13-14 season, the New York Knicks had made the Conference Semifinals after finishing with a 54-28 record in 2012-13. But trading for Andrea Bargnani proved to be a disastrous move, and they finished with a 37-45 record and out of the playoff berths.

This marked the only time all 3 of these franchises missed the playoffs in the 71-year history of the NBA.
