Defensive Tackles:
Osa
Gholston
Hanking
Massi
Fehoko
On the bubble: Gallimore, Bohanna
I think that is accurate.
Also, if you consider salaries, Gallimore, as a former 3rd round pick in his 4th year, takes up almost 3 mil in cap space this season, and if released, could save close to 3 mil in cap space. That's not huge money, but it's not a little either.
Osa and Gholston are under 1.4 hits. Mazi is 2.4. Hankins is 1.1 and Bohana is under 1. So Gallimore is our highest paid interior DL as of now, so money may play a factor. Personally, I would have rather kept Watkins at the 1.75 he signed for, and cut Gallimore, which would have saved over a million in cap space. There are still a few FA's out there as well. Shelby Harris and Chris Wormly are still FA's, though they may be more in ther Gholston/Fehoko mold, than the Osa/Gallimore mold. Both are far better than Gallimore though, so if they would sign for min salaries like Hankins, they would both improve the rotation and save us cap space.
Not a huge Bohana guy, but he may be worth a PS spot at his contract and the fact that he could be a long term Hankins replacement, plus give us some depth at the 1 tech which is never a bad thing. Mazi/Hankins on the 53 and Bohana on IR or the PS would be nice.
Injuries may play a factor as well.
