I agree, although Mark's blocks per game were even unique for that era. The year he averaged 5.6 blocks per game, the next closest was Hakeem who averaged 2.7. There were others who had very high block per game seasons, but none who were as consistent as Eaton.The problem when you try comparing blocks from one era to the other is that the game has changed completely. In Eaton's era the game was far more condensed and led to so many more shot block opportunities. Put Rudy in that era and he is definitely in that 4 block a game range.
