Raji hasn't been non existant at all IMO. He just plays a position that doesn't fill the stat sheet. The defense was a lot worse those games that he missed
They are other NT that make an impact so i don't really wanna hear the whole "He plays a position that doesn't get noticed" type of argument. He doesn't get any push and rarely gets any pressure. There is a reason our DL has been mediocre at best.
