Fun fact about the legitimate G.O.A.T. of the NBA, Mr William Felton Russell, is that while his adversary Wilt Chamberlain collected more records, Russell cared more about winning. The reason this 51 rebound night is listed as a "then record" is because later in 1960, Wilt topped that mark with 55 rebounds. But Wilt's 55 rebound game came in a loss to... yeah you guessed it Russell and the Celtics. The ring is the thing. It's about winning and not stats. That's why Bill Russell is the legitimate greatest of all time.
