The guy who organized the San Antonio Spurs post-Game 7 mega-bash was their very own coach -- who paid for a fancy steak dinner, drinks and a party bus to thank his players ... TMZ Sports has learned.
Our Spurs sources tell us ...Coach Gregg Popovich wanted to show his appreciation to his players after they were eliminated from the playoffs Saturday night ... so he organized a night out in Hollywood.
We're told he set up a post-game steak dinner at Mastros in Beverly Hills ... and paid for EVERYTHING (and this place sure as hell ain't cheap).
Afterward, Pop hired a party bus to chauffeur the guys to Project Club L.A. -- and encouraged the team to "take their minds off the game and let loose" ... not wallow in their sorrows.
The guys did just that ... some harder than others ... and as we previously reported, Tim Duncan had to carry at least ONE of his over-intoxicated teammates back to the bus.
Pretty cool boss.
