It is totally up to SEA, all Wilson could do is pout and refuse to report if they choose to go that route, there is nothing to pull off. I imagine they will get something done to create good will, I personally would love to see Wilson play with another team, or even Seattle with a middle of the league defense. I just don't think he is the type of guy that can carry a team. I really think he is CK kinda good, making plays on short fields, with leads, and freedom to take risks due to the a stellar defense having his back.
I like Wilson's ball security and his playmaking, but he has ranked 28,28,22 in yards/game over his career. He has never needed to or been asked to carry a team. Cold hard fact is he will likely get overpaid, nothing he has done bears out a top 3-5 contract. When Sea d breaks up, which won't be long with the big contracts coming, he will need to answer the call to start putting up top 5 #'s which I don't see happening.
