Like, I think it was t-shirt in another thread, I have gracefully given up trying to guess what the Pats will do. But it is interesting to think about the tradeoffs and see how they make them.
As F.B.N. mentioned, it will be interesting to see how the issue of whether Seymour "is" a DE or DT plays out. Officially (all web sites: Pats, NFL, CBS, ESPN, SI) Seymour is listed as a DT. You can guess that the Pats will try to leverage that, but I can't see it really having any effect - Seymour will be considered by ALL other teams as in the DE contract level and so the Pats really don't have a choice, either.
While, as I say, I won't be surprised at much of anything, I actually will be more than a little surprised if the Pats can do an extension with Seymour this year.
Considering that this is a funny money year, any contract that Seymour and his agent would insist on relative to this year's money has to be out of sight for the Pats. I really don't think they will overpay for anyone, even Seymour.
And the temptation for Seymour's agent, not to mention probably Seymour, to test the open market seems irresistable. I really don't think Seymour will settle for a hometown discount of any amount.
From the Patriots standpoint, while this is a funny money year, next year has all the earmarks of being a much tighter year in terms of free agent money available, so the Pats will be slightly more likely to get a better deal for Seymour next year. However, it only takes ONE team to pay huge bucks and there is likely to be at least one team with the money to do so.
The one leverage that the Pats have is to use, or say they will use, the franchise tag - ESPECIALLY if they can make it stick as a DT franchise amount. If they do that as a DT, I'm sure that will end up in arbitration with even a real possibility that, if he doesn't win, Seymour would refuse to sign the franchise offer and just sit out a year.
