Wilfork has earned his money this year and also brings value above and beyond his play. He may be the most highly respected player on the team. If not, it's close. He has been a bedrock player and, even in Foxboro, some accomadation has to be made for being a great player/teammate/lockerroom presence. This is a core guy who has toed the line and helped lead for BB for more than a decade, like Bruschi, Troy Brown et.al.. I think that's the difference between him and Seymour and why one player will be viewed as a core all-time Patriot great and the other just a great player who played for the Pats. He won't be cut.
Money for Gost will be about 4 mill/yr. I think resigning him will depend on the strength of the kicking prospects available. Gost has been fantastic and deserves his money, but I'm not sure BB will pay any kicker that much. See Vinatieri, Adam for details.... For non-core players, it's not just about player value, it's also about replacement cost. If BB can find 90% of Gost for 3.5 million less, he may move on. He's done it in the past.
