Starters: Dan Williams, Justin Ellis
Depth: Stacy McGee, Leon Orr
Dan Williams is heading into his second year with the team since signing a free agent contract from the Cardinals. All others are original Raiders, with 2014 4th round pick Justin Ellis starting along with 2013 sixth round pick Stacy McGee and 2015 undrafted free agent signee Leon Orr who spent much of last season on the practice squad before being called up to the active roster late in the season.
Condition: Touch and go
Williams was a great signing by the Raiders and had a very nice season last year, leading all Raiders defensive linemen with 48 combined tackles. Ellis did a fair job starting at each tackle spot. Techincally speaking, however, both players are best suited at nose tackle and the Raiders are best served with them in a rotation. There is some flexibility there, with Williams able to start at nose in the 3-4 and move to defensive tackle 4-3 with Ellis joining him on the line.
Williams' weight came down in the hopes it would allow him to be an every down player at either defensive tackle position, but a true pocket pushing 3-tech he is not and his 0.5 sacks last season bear that out. The Raiders may not have a pure 3-tech DT on the roster. Instead they have a few defensive linemen who can play two different positions, with Mario Edwards Jr and Denico Autry able to switch from DE to DT in different alignments.
Versatility is great, but adding a true starting 300-pound defensive tackle who can also rush the passer would be a valuable addition.
Orr has shown some promise and could take on a larger role. He is a massive 6-5, 320 which is how Jack Del Rio likes his DT's and the potential is there, but as yet unproven. McGee has never really shown himself to be much of a contributor and is coming into the final year of his rookie deal.
