Players: DT Vince Wilfork, DT Marcus Forston, DT Armond Armstead, DE Jake Bequette, DE/DT Jermaine Cunningham, DE Chandler Jones, DE Marcus Benard, DE Michael Buchanan, DE/DT Justin Francis, DT Cory Grissom, DT Tommy Kelly, DE Rob Ninkovich, DE Jason Vega, DT Anthony Rashad White, DT Joe Vellano
Analysis: This is a deep unit, starting at the top with Wilfork, who continues to be the backbone of the team. He plays the meanest, nastiest football imaginable, but somehow, he does it like a gentleman. Another classy aggressor is Ninkovich, who's emerging as a reliable juggernaut and an efficient clutch performer down the stretch.
Jones showed great ambition in the first half of his rookie season, storming out of the gate with an assortment of dazzling moves, which helped him notch six sacks and three forced fumbles. The second half of his season fell apart with injuries and his downtick lingered into the postseason. Expect a profound second-year jump.
Forston, Francis and Kelly have great shots at becoming key contributors in 2013. Benard had 7.5 sacks for the Browns in 2010 and he's only 27 years old, he has an opportunity to make some noise.
Grissom ranked as the No. 1 defensive lineman on the list of top undrafted rookie free agents of 2013, as compiled by Gil Brandt, senior analyst for NFL.com. Fellow rookie Buchanan is flying under the bubble radar right now, but his skill level is tremendous and he could breakout early.
