When Joe Lacob and Peter Guber paid $450 million for the Golden State Warriors in 2010, the sports world was left scratching its head. The first major team purchase for the venture capitalist and Hollywood producer, who outbid billionaire Larry Ellison, then the world’s sixth-richest person, set a record price for an NBA franchise. It was hardly anyone’s idea of a crown jewel. Forbes valued the team at $315 million seven months earlier, No. 18 in the league. The team had been to the playoffs just once in the prior 15 years and had inconsistent attendance at its 44-year-old arena. No one is questioning the deal now. Today the Warriors are valued at $3.5 billion, the third most valuable team in the NBA behind the New York Knicks ($4 billion) and Los Angeles Lakers ($3.7 billion), a ten-fold appreciation since 2009 that has proven to be the decade’s best team investment in all the major sports leagues, including the NFL, NBA, MLB, NHL and international soccer, on a percentage basis.
