Bill Russell is rightfully regarded as the best defensive big man in league history. Well, second to Russell in this category is Hakeem Olajuwon. Most hoopsters are aware that Olajuwon is the all-time blocks leader, but little do most know that Hakeem, at #8, is the only center in the top 10 (and 15, 25, 40) on the all-time steals list. Next closest center is David Robinson at #44. Hakeem will likely go down as the only player to ever amass 2000+ steals (2162) and blocks (3830)
