There is definitely going to be a slight downward adjustment in salaries next year. Not much, but the Pats should be in good position. Though they are going to tie up money with JC Jackson and with Thuney. I expect both of them to be signed to long term deals. Hopefully, they can get Jackson for a 5 year deal and Thuney on a 3 or 4 year deal. I fully expect them to draft another center in the draft regardless of whether they bring back Andrews or slide Thuney over. Personally, I'd slide Thuney to center and put Onwenu at LG with Herron/Cajuste/Draft pick battling it out for the RT position. I've not seen anything to make me believe that Thuney wouldn't be an All-Pro center if the Pats moved him there full time.
I expect that Eleumenor, Andrews, White, Butler, and Wise to sign contracts with other teams that will be part of the compensatory pick equation. There could be others like Calhoun who may or may not slip into the equation. Hopefully, the Pats can bring back Byrd, Guy and Carl Davis as well as Thuney and Jackson.
