• Hakeem Olajuwon (March 29, 1990): 18 points, 16 rebounds, 10 assists, 11 blocks
• David Robinson (February 17, 1994): 34 points, 10 rebounds, 10 assists, 10 blocks
• Nate Thurmond (October 18, 1974): 22 points, 14 rebounds, 13 assists, 12 blocks
• Alvin Robertson (February 18, 1986): 20 points, 11 rebounds, 10 assists, 10 steals

The quadruple-double has only been accomplished, or should I say recognized, four times in NBA history. I said "recognized" because Wilt Chamberlain and Bill Russell have done it plenty of times before blocks were being recorded and Hakeem Olajuwon had two in the same month but the league took the first one away, accusing the Houston Rockets of stat-padding.

What many people don't know is Hakeem's Houston teammate, Clyde Drexler, also almost pulled off the milestone in 1996 but was "robbed" of an assist. The assist in question comes at the 2.26 mark of the above video. Without the assist, the 34-year-old Clyde was left with the petty line of just 25 points, 10 rebounds, 10 steals and 9 assists. Just retire Clyde!

What many people also don't know is that a decade earlier, a high(er)-flying Drexler was just one rebound away from a quadruple-double in a game against the Bucks. His final stat line on that night was 26 points, 11 assists, 10 steals and 9 rebounds! Pretty impressive for a guy who never looked up while dribbling the ball.

And impressive are these flirting with quadruple-double lines?
