The National Basketball Association's (NBA) block title is awarded to the player with the highest blocks per game average in a given season .

To qualify for the blocks title, the player must appear in at least 70 games (out of 82) or have at least 100 blocks . This is the requirement since the 1974--75 season, with requirements changing with the schedule length several times before that . </P> <P> Mark Eaton holds the all - time records for total blocks (456) and blocks per game (5.56) in a season; both achieved in the 1984--85 season . Manute Bol holds the rookie records for total blocks and blocks per game when he had 397 and averaged 5.0 in the 1985--86 season . Among active players, Hassan Whiteside had the highest season block average (3.68) in the 2015--16 season . </P> <P> Kareem Abdul - Jabbar, Eaton and Marcus Camby all won the most block titles, with four . George Johnson, Manute Bol, Hakeem Olajuwon, Dikembe Mutombo, Alonzo Mourning, Theo Ratliff, Dwight Howard, Anthony Davis, and Serge Ibaka have also won the title more than once . Both Mutombo and Camby have also won the most consecutive block titles, with three . Two players have won both the block title and the NBA championship in the same season: Bill Walton in 1977 with the Portland Trail Blazers and Abdul - Jabbar in 1980 with the Los Angeles Lakers . </P>
