Dikembe Mutombo, one of the greatest to have never won the championship. A four-time NBA Defensive Player of the year, a record he shares with Ben Wallace, Mutombo is regarded as one of the best shot blockers of all time. He is listed second in the NBA All-Time blocks registering 3289 over the course of his 18-year career.

Using his tall stature to his advantage, he was consistent with his blocks and rebounding. He averaged 2.8 blocks and 10.3 rebounds per game during his career.

Mutombo's celebration after each successful block became infamous as he would taunt his opponent with the index finger like a parent disapproving their child's act of disobedience. His long elbows also caused injuries to players both opponents and teammates. He was picked three times for the NBA All-Defensive first team along with being three-time NBA block leader and two-time NBA Rebounding leader.
