Legends like Bill Russell and Wilt Chamberlain would have almost certainly been near the top of this list, but blocks have only been recorded since the 1973-74 season.
As a result, Kareem Abdul-Jabbar, with his 10 trips to the NBA Finals, comfortably sits atop the leaderboard for most blocks in NBA Finals history.
