He didn't invent it he's just the first who used it in a game. It's basically a basketball defensive technique. Bump and run was invented by a basketball player, KC Jones, who won multiple championships in college with Bill Russell at U of San Francisco. He was a late round pick in camp with the LA Rams in the 50s, came up with bump and run because that's how he was playing college basketball on defense. Jones taught it to the coach, Jack Faulkner, who a few years later taught it to Willie Brown at Denver, who took it to Oakland when he was traded there in 67, where it finally made it into a game. Ironically, KC Jones never played a game for the Rams and then went to play for the Celtics, and the rest is history.
