The obvious gone are guys like DeGuera and Runyan. Neither is a guy who has developed. They need to be replaced obviously. Probably Wagner as well.
On D there are no "obvious" guys like that and a lot depends on how Gutes and the new D coordinator want to approach things. McDuffie's play probably makes Campbell expendable in a salary move. Savage probably should be finished here, but get the right system and he has value still. LVN needs snaps and Enagbare is solid as a 3rd guy, but Preston is a pro. Cutting Preston to save minimal $$ seems foolish to me. Especially when you can slide Gary or LVN inside on obvious passing downs.
I guess what I'm saying is that nothing would shock me at this point. We could end up with Bak, Jones and Preston all on next years roster if chips fall into place. Or, all 3 could be gone. MiLF loves Campbell so is he gone for sure? This is going to be a very interesting off season. Hell, with a weak TE draft I could even see them bringing back DeGuera.
