How did Ravens defensive linemen stack up to rest of NFL in 2018?

The Ravens returned to the playoffs for the first time since 2014, but where did their players stack up across the NFL in 2018?
Whether it’s discussing the Pro Bowl or determining postseason awards, media and fans spend much time debating where players rank at each position, but few watch every player on every team extensively enough to form any type of an authoritative opinion.
Truthfully, how many times did you watch the offensive line of the Detroit Lions this season? What about the Oakland Raiders linebackers or the San Francisco 49ers cornerbacks?
That’s why I appreciate the grading efforts of Pro Football Focus while acknowledging these rankings shouldn’t be viewed as infallible or the gospel of evaluation. I can respect the exhaustive effort to grade players across the league when most of us watch only one team or one division on any kind of a consistent basis.
Below is a look at where Ravens defensive linemen ranked at their positions followed by the positional outlook going into 2019:
Offensive linemen
Linebackers
Tight ends
Brandon Williams
2018 defensive snap count (including postseason): 517
PFF ranking: 33rd among interior defenders
Skinny: Williams ranked 22nd among interior defenders against the run, but opinions have varied on his value since before he signed his $52.5 million contract two years ago. The nose tackle played a major part in Baltimore ranking third in yards per carry allowed, but he played just 50 percent of defensive snaps.
Brent Urban
2018 defensive snap count (including postseason): 522
PFF ranking: 49th among interior defenders
Skinny: Urban played all 16 games in a season for just the second time in his career and did the dirty work at the 5-techniqe end spot, but he made few splash plays with only a half-sack and two tipped passes. The Ravens would likely be interested in re-signing Urban again to a short-term deal.
Chris Wormley
2018 defensive snap count (including postseason): 401
PFF ranking: 67th among interior defenders
Skinny: The 2017 third-round pick made six starts prior to the bye week and established himself as a regular member of the game-day rotation, but his playing time declined after the bye as he made less of an impact. Wormley could find himself playing more 5-techinique if Urban departs via free agency.
Michael Pierce
2018 defensive snap count (including postseason): 389
PFF ranking: fifth among interior defenders
Skinny: Despite being slowed by a foot injury early in the year, Pierce thrived in his third season, providing more ammunition for critics of the Williams contract. The former undrafted free agent is positioning himself for a strong payday after 2019, especially if he can offer a little more as a pass rusher.
Willie Henry
2018 defensive snap count (including postseason): 82
PFF ranking: n/a
Skinny: Henry was on his way to becoming the starting 3-techinique defensive tackle before August hernia surgery cost him the first four games of the year and an October back injury ended his season. The Ravens missed his inside pass-rushing ability, something he’ll hope to reestablish in a contract year.
Patrick Ricard
2018 defensive snap count (including postseason): 47
PFF ranking: n/a
Skinny: The versatile Ricard also took snaps as a blocking fullback, but he wasn’t active after Week 12 and the surfacing of past racist and homophobic tweets didn’t help his perception. His ability to play on either side of the ball helps his roster standing, but he’s far from a lock to make the team in 2019.
Zach Sieler
2018 defensive snap count (including postseason): 17
PFF ranking: n/a
Skinny: Ozzie Newsome’s final draft pick last April, Sieler spent most of the year as a game-day inactive, but the Ferris State product flashed enough last summer to warrant the organization keeping him on the roster. Sieler could move into a more significant role in 2019, especially if Urban signs elsewhere.
2019 positional outlook
Even with Urban being an unrestricted free agent and Pierce a restricted free agent, this remains one of the better positional groups on the roster going into next season. The Ravens would benefit from Wormley and Sieler taking a step forward to become bigger factors as 5-technique players, but they’ll again be strong inside with Williams, Pierce, and a returning Henry. It’s worth mentioning how frequently linebacker Za’Darius Smith moved to the interior line to rush the quarterback in obvious passing situations this past season, so Baltimore will have its eyes peeled for an interior lineman who can pressure the pocket. It will be fascinating to see how Pierce and Williams play in 2019 and how that might impact the organization’s plans for 2020 and beyond. Pierce is 3 1/2 years younger and will be an unrestricted free agent while the Ravens could conceivably move on from Williams’ deal next offseason.
