Arriving late to the Revis party, but I hadn't seen this around on the site. Andrew Brandt at The MMQB states that the big differentiator was the Jets willingness to offer a $6M no-offset guarantee for the 3rd year of the contract:
"The key marker in the Revis contract is neither the $39 million overall guarantee nor the $70 million total value. Rather, it is the $6 million no-offset guarantee in the third year that is the differentiator in the deal (and was so with the Patriots). Having the first two years guaranteed is standard fare for top free agents; Revis’s $6 million third-year no-offset guarantee is powerful."

That's a lot of cabbage to be potentially paying to Revis if he's playing for someone else. I'd love it if he had stayed with the Pats but I'm glad they didn't give up a contract like he signed with the Jets. Guy was going to go after the money and I have no problem with that, or anything that he said. And his uncle runs that operation so if he has 2 good years, I bet he holds out the third year. Again, more power to him if he wants to use his leverage, but I'm glad it's not going to be at the Pats expense.
Plus, Kraft even said it (and I was surprised he did): Pats have 3 young defensive players to extend.
I've been watching the Pats this offseason, having to pick and choose their guys because of cap space, losing guys that they liked, but not at their current contracts. My take is that the media that stated last offseason that the Pats should have been "all in" like the Broncos had it wrong:
The Pats WERE all in. And it worked!
But now they have to let some guys walk. Oh well, that's what happens when you're all in. But the great thing is that the Pats managed to go all in without actually sacrificing next season OR the long term. Because they lost some short term players, but they don't have dead money and they haven't lost their ability to maneuver.
And although it's possible the defense may take a step back, I think it's possible the offense takes a step up, now that they've all worked together for a season.
