Over the past three seasons, Los Angeles Clippers owner Steve Ballmer has spent more money on player salaries than all of his rivals except the Golden State Warriors. The Clippers’ payroll topped $200 million this season alone, a staggering sum that reflected only a small percentage of the former Microsoft executive’s investment in his passion project. Ballmer paid a then-record $2 billion to buy the Clippers in 2014, and he has spent an estimated $2 billion more to construct Intuit Dome, his futuristic new arena that opens in Inglewood, Calif., next season.
