Ok, Ok, I know how stupid this sounds on paper but hear me out:
The Jets have an absolutely untenable Cap situation that Idzik VERY MUCH would like to get rid of, especially Sanchez's albatross of a contract ($8.25M guaranteed to basically suck the life out of Jets fans). Revis is gone after next year unless Idzik pulls Cap magic anyway (and his Cap figure is huge as well).
Solution? How about a new QB at a very team friendly deal? The Seahawks are able to absorb Sanchez's TERRIBLE contract (because of Wilson's GORGEOUS contract), and in the process get Revis in the mix. Flynn's contract is much smaller and has almost no guaranteed money anymore (meaning they can easily cut him if he sucks. If he works out, then even better).
NYJ: Revis gone (loss), Sanchez & Contract gone (HUGE win), Flynn & Contract in (maybe great? maybe not?)
SEA: Revis in (win), Sanchez & Contract in (Loss, but stomach-able), Flynn out (no effect).
