Founder/creator of the San Antonio Spurs, Angelo Drossos. Don't know much about him other than he gave up ownership in 1988 and died in 1997 from some form of palsy.
You have to tip your hat to this guy, he is the one that turned over the money even when he was hardly making any to keep this franchise alive and going. Without him there is no Gervin, Robinson, and Duncan making history.
