Some of my thoughts:
1. Nobody is trading for Vince Wilfork, the draft is very deep at DT and he is old with a huge cap hit. Wilfork is going to be interesting, last season I said to keep him, this year though I am not sure where I stand yet.
2. Nobody is trading anything higher than a 5th round draft pick for Jerod Mayo; he has played 10 games in the last 2 seasons and carries a huge cap hit. Belichick loves Mayo, probably his favorite player in the past 5 years outside of Brady so I cannot see him cutting ties with him, Mayo is also dedicated to the team and winning, he will do what needs to be done.
3. Amendola was very good during the postseason, I am not sure he will be back, he might want to be a featured WR and with Edelman here that is not going to happen, so why would he take less money to play here in a role that he likely feels he is too good of a player for?
4. Browner has a big cap hit and really was not anything special this season, he will not be here for $5.5M they will either rework the deal or he will be gone.
5. Revis is not going anywhere, they will pay the $20M before they let him walk and then franchise him again in 2016 so it is essentially control of Revis for 2 seasons. Not to mention they take a $5M cap hit even if they cut him, Revis is not going anywhere I am almost certain of that.
6. I think Ayers will be back, I think he is a long-term replacement for Ninkovich and security if they cannot come to terms with Chandler Jones on an extension.
7. Casillas will be back also, he is a good role player and can be retained for short money.
8. I am not sold on Vereen returning, they drafted James White for a reason and most likely, they viewed him as that 3rd down back. Vereen was a ghost when Woodhead was around so do not be surprised to see White take over. They also have Bolden who is serviceable as a 3rd down RB.
