Seattle lost both starters at defensive end this offseason but did a good job of mitigating the losses. Michael Bennett and Cliff Avril both return after playing major roles on the Super Bowl team last season, and they are the likely starters in 2014.
Behind them will certainly be fourth-round selection Cassius Marsh, who should see plenty of action in the situational pass-rusher role that Avril played in a year ago.
After that, it is difficult to project the rest of the depth chart since it is still unknown how Seattle's defensive scheme is going to change as it evolves away from having Red Bryant at the 5-technique position. If they stay big at the position, Gregg Scruggs and Jesse Williams figure to both be given the chance to earn playing time there.
On the lighter side of the spectrum are Benson Mayowa, Kenneth Boatright and Jackson Jeffcoat, all of whom have potential to be productive situational pass-rushers.
The situation at defensive end gets even murkier once the linebackers are added into the mix. Bruce Irvin, O'Brien Schofield and Mike Morgan are all capable pass-rushers who have been used at defensive end at times over the last two seasons.
Defensive tackle is setting up to be an intense roster battle as well. Starters Brandon Mebane and Tony McDaniel return, and defensive end Michael Bennett is certain to play plenty of snaps at the position. Behind those three, though, there is a large group of players that are all vying for two roster spots.
Michael Brooks, Dewayne Cherrington, Jordan Hill and D'Anthony Smith each spent at least part of last season will Seattle. Williams and Scruggs were with the team as well, though both missed the entire year with injuries.
Recently added to the mix are sixth-round pick Jimmy Staten and undrafted signee Andru Pulu. These two will be given every chance to try and make the team over those listed above because of their low cap numbers and remaining years of team control.
Overall, Seattle's defensive line appears to have a great combination of both talent and depth.
