Makes sense if true. Sherman, Peterson, and Haden have pretty much set the market for elite corners at $13-14M per year. The Pats may feel comfortable matching that on a backloaded contract with a lot of guarantees, provided that they think they cap will rise dramatically. If they can convince Revis to take $12M per year over the life of a long-term contract, it becomes basically a no-brainer, even if they have to guarantee a lot of it.
Revis is a hardworking, consistent veteran who's absolutely elite at a high-impact position. He's exactly the kind of guy who the Pats are willing to pay long-term, premium money for. If they can get him and McCourty extended this year, that'll give them another 1-2 years before they have to worry about Chandler Jones, so the core of the defense will be pretty much locked up.
