Here is a fun lil tidbit I just ran accross
The term “sack” was first popularized by DE Deacon Jones in the 1960s. He compared the devastation an offense felt after letting up a sack to that which a city felt after being sacked.
“Sacking a quarterback is just like you devastate a city or you cream a multitude of people,” Jones famously stated. “It’s just like you put all the offensive players in one bag and I just take a baseball bat and beat on the bag.”
Before the term was coined, tackling a quarterback behind the line of scrimmage was known as “dumping the passer”.
