By collecting three block shots in Game 4's clincher against the Los Angeles Clippers, San Antonio Spurs Tim Duncan moved closer to becoming the All-time leader in playoff blocks.

Duncan has blocked 468 shots in 184 playoff games and needs only four to catch Hakeem Olajuwon for second on the all-time playoff list. He is just eight behind all-time leader Kareem Abdul-Jabbar.

However, blocks did not become an official NBA statistic until 1973-74, after two of the game’s greatest shot blockers, Bill Russell and Wilt Chamberlain, had retired.

Nonetheless, Duncan jokes that he already is the All-time leader, both regular season and playoffs, in a special category.

"I’m pretty sure I am the all-time leader in blocks without leaving one’s feet," he said earlier this season.

San Antonio's big man is currently 5th in playoff rebounding list with 2,249 rebounds, 232 boards behind Jabbar and 7th in playoff scoring list behind Jerry West.
