Guaranteed:
Williams is the best defensive tackle on the team and will now take over as leader of the defensive line with Haloti Ngata gone. He's guaranteed to be on the roster.
Timmy Jernigan
Jernigan started to break out when Haloti was gone next year and he will get a chance to build on that in 2015, as he will now be a full-time starter on defense.
Carl Davis
Davis has the potential to be the steal of the draft. No way he isn't on the team.
Probables:
Chris Canty
Canty is the only defensive lineman above the age of 26.
