Wilt Chamberlain has twice grabbed 50 rebounds in a single game! A player has previously provided 30 assists. Four double-doubles have been recorded. A quintuple-double has never occurred and has never come close, making it the most difficult stat-based achievement in NBA history. Chamberlain's first such performance came on March 1, 1962, when he had 51 rebounds against the Syracuse Nationals. The second time was five years later on January 4, 1967, when he had 50 rebounds against the Philadelphia 76ers. He also provided 30 assists on both occasions. It should be noted that at the time of these games, there was no limit on the number of field goals or free throws a player could provide; only limited to the number of minutes they could play during each period. Thus, Chamberlain could have just as easily had six or seven assists or even three or four blocks - although neither of those events had yet been invented! In addition to his ability to grab an incredible amount of rebounding yardage, Wilt Chamberlain was also capable of putting up huge numbers in other categories. His season averages are currently recognized as being "record-breaking". However, at the time they were set, they had not been surpassed since then and are now considered historical benchmarks.
