Top 30 Best Defenders in NBA History

19. Alonzo Mourning

Alonzo Mourning was one of the best shot-blockers that we have ever seen in the NBA. What made Mourning really special was his ability to block shots with a soft hand so that he could keep the ball in bounds and start a fast-break for his team. Mourning’s average of 5.46 blocks per 48 minutes is the best mark in the history of the NBA.
