On June 3, 2013, head coach Doc Rivers was allowed out of his contract to coach Los Angeles Clippers and the Celtics were given a 2015 unprotected first round pick as compensation. A few days later, Paul Pierce and Kevin Garnett (after waiving his no-trade clause), along with Jason Terry and D. J. White, were traded to the Brooklyn Nets for Keith Bogans, MarShon Brooks, Kris Humphries, Kris Joseph, Gerald Wallace, and three future first-round draft picks (2014, 2016, 2018), with the option of swapping 2018 pick with Brooklyn's 2017 pick. The deal was later approved by the league on July 12, 2013, effectively ending the 'Big 3' era and marking the start of a youth movement for the team. One of the leaders of said movement was 2013 draft pick Kelly Olynyk.
