55 by Wilt Chamberlain vs. the Boston Celtics on November 24, 1960
Fans freak out today when Kevin Garnet gets 20 rebounds in an entire game. Wilt had that amount
15 minutes into the game. What makes this even more remarkable a feat is that he wasn't doing this
against a bunch of Rec-Spec wearing white guys who were all shorter than 6'6". He was facing off against Bill
Russell in this game, the self-proclaimed best rebounder ever. Wilt's stats would say otherwise though.
Most teams don't miss 55 shots the entire game, so breaking this record is likely impossible.
