In American football, an interception (INT), also known as a pick, occurs when a pass intended for a player of the same team is caught by an opposition player, who then gains possession for their team.
[5][6] In addition to the NFL interception leaders, league record books recognize the interception leaders of the American Football League (AFL), which operated from 1960 to 1969 before being absorbed into the NFL in 1970.
[9][10] Prior to that, Dan Sandifer of the Washington Redskins and Spec Sanders of the New York Yanks jointly held the record, earning 13 interceptions in 1948 and 1950 respectively.
This was first achieved by Everson Walls, who led the league in interceptions in 1981, 1982, and again in 1985.
[13] Ed Reed was later able to match Walls by leading the league in 2004, 2008, and 2010.
