It's 100% true. The 16 million dollar (or 1 million per game) deal that Revis signed was strictly year to year. Not too shabby coming off an ACL injury where it wasn't even guaranteed that he'd definitely be playing in game #1.
As far as him being "stupid," I'm not so sure I'd see it that way when the rest of the better CBs in the game are all making 30-40-50% of what he made this year.
I'm guessing that he could give a damn less whether or not he goes to another team, especially after just making 16 million dollars. He knows he has a guaranteed job with a double digit salary somewhere in the NFL.
Not much difference between making 16 last year and 10 this year, in comparison to 13 + 13, is there?
