NBA Top 10 Blockers All-Time

Guess the 10 best blockers of all-time in the NBA. The top 10 is not a list of the 10 players with the most blocks, but the best players in the action of blocking. Criteria are the amount of blocks, regularity and high blocks per game rate during the all career, courage and not being afraid trying the block in front of the best players where you could get posterized, where they can position themselves to get a block. Blocks have been counted since 1973-74, but players playing before that can be in the ranking. The ranking is also not just a list of center, of positinos can be represented.
