#8 - Bill Russell
If there was ever a ‘kryptonite’ for the original superman, Wilt Chamberlain, it was Bill Russell. Wilt could simply not be stopped, unless he was going head to head with Russell. The road to the title in those days went through Bill Russell, and only a very select few got through him. Although they didn’t record blocks back when Bill Russell and Wilt Chamberlain were playing in the NBA, there are some tremendous stories circulating, among those who were fortunate enough to see them play live, that both giants blocked shots by the dozens. Although we have to take our elders word for it, they both did enough on defensive rebounds alone to land them on this list. Russell averaged 22.5 rebounds per game over the course of his career, which is more than 11 per game over the third all time on that list. The Celtics were a very tough team to score on in those days, and it all started and ended with Russell anchoring the paint.
