record sacks in football

"Record" is both a noun and a verb. When a musician records (verb) a song, he makes a tape or CD of the song he is playing. The CD, or a copy of it, that is sold in stores or on the internet is called the record (noun).

Same in sports.When a player makes a notable play, such as a goal in hockey, he records (verb) the goal. At the end of the game, or the season, or the end of his career, the number of goals he recorded (verb) becomes part of his record, (noun).

If, at the end of his career, the player has recorded more goals than anyone else in history, we say that he has "the record" for goals scored in a career.

Same thing applies to any notable play in sports that sports followers keep track of, such as sacks or touchdowns in football, home runs in baseball, points in basketball, etc.
