Well, I'll take a stab at it.
First, I don't think this is zone coverage. I think those corners and backers are in man coverage, and playing uncharacteristic outside-in technique because their help (high free safety, zone dropping lineman) is inside. If you look at the Jets CB on Branch, he's basically at the line of scrimmage. Running a tight jam in a Cover 1 zone is almost incomprehensible, you need at least a Cover 2 to reach the fade. So I'm thinking this is a Cover 1 man, Harris *has* Woodhead at the snap and sees a HUGE clear read in front of him and so goes charging into the backfield.
That leaves Devito (the fire zone player) and Revis, whose man at the snap is Welker, who he dutifully follows weakside on Welker's rub route. Devito's zone drop is supposed to leave a Pats lineman blocking air and so put the Jets a man up on the play, but that extra lineman just ends up blocking the overaggressive Harris. This is also why Revis and Devito don't switch responsibilities; it's actually the Revis and Harris who would switch responsibilities (if allowed in the Jets scheme), and Harris is in no position to cover anybody.
Devito in coverage isn't supposed to actually cover any one, he's supposed to be big and tall and as deep as possible in order to screw up Brady's throwing lanes so Erik Smith, the deep safety, can stay over top. The thing the Jets don't want in that situation is a crossing route from one of the receivers. But because Harris is absentee and Devito takes a deep drop, Woodhead can get out of the backfield underneath the fire zone, and Brady doesn't have to throw over or around any 6'4" lineman to complete a crossing route into space.
