Javon Hargrave is quietly having a breakout season, and quickly becoming one of the best interior defensive linemen in the game. He has registered 6.5 sacks so far this season, which places him among the top ten leaders for sacks by interior defensive linemen in the NFL, and the only one listed as a nose tackle. What makes this achievement even more impressive is the fact Hargrave has put up that number in about half as many overall snaps as the players currently ahead of him on the list.
Hargrave is arguably the Steelers most improved defensive player, not taking anything away from free safety Sean Davis' improvement this season.
