The master of the finger wag was the best shot blocker of his era, and indeed Dikembe Mutombo also deserves credit for his incredible longevity on the court. The native of Congo actually wanted to become a doctor when he arrived at Georgetown on a United States Agency for International Development scholarship, but John Thompson quickly took note of the 7'2" giant and developed him into a defensive juggernaut.
Mutombo was a force right from the start of his NBA career, averaging a career-best 16.6 points per game as a rookie; over the first 10 years of his career, the center posted a double-double each season, averaging 12.4 points, 12.4 rebounds, and 3.5 blocks per game over that stretch. Along with Ben Wallace, Mutombo is the only player to win Defensive Player of the Year honors four times since the award's inception in 1982-83.
