The NFL is looking into a number of rules changes this offseason and reportedly will consider making defensive pass interference a 15-yard penalty.
The penalty is currently a spot foul.
If a change is made offenses would have far less to gain by throwing deep to try and draw a penalty from a defensive back downfield.
Defensive pass inference was called 266 times this past season, according to Pro Football Reference. That's more than once per game for an average of 18.09 yards per game.
