2. Dikembe Mutombo
Dikembe Mutombo’s finger-wagging celebration after a blocked shot is one of the most infamous moves in the history of the sport. Mutombo led the NBA in blocks three times in his career and finished his career with an average of 2.8 blocks per game. Mutombo won four Defensive Player of the Year Awards and is one of the best defensive players we have ever seen.
