Whelp, nothing I can do here but get the tape out and lead some "image" study. Football 101 is now in session, TA unoriginal presiding.
Here we see the formations well before snap. Of especial note concerning pass coverage is the attitude of the outside cornerbacks; here one can clearly see Kyle Arrington, #24 in your playbook, is lined up outside the receiver and is angled so he may observe the quarterback. This is a good tell for zone coverage. The classic man look would be Arrington inside or on top of the receiver, in this case Nate Washington, #85 in your playbook, and facing him. You'll no doubt note that Devin McCourty, the near corner, has adopted an even more severe attitude than Kyle Arrington.
Tavon Wilson, #27, who is in for the recently sidelined Pat Chung, has walked down on top of the slot. Not pitctured is Steve Gregory, who is deep in the middle of the field.
From Jake Locker's point of view, the coverage picture is confused. The corners seem to be in Cover 2 on the flats, but there is only one safety high.
The thing to notice here is that, by the time of the snap, Tavon Wilson has already backed off the slot several yards. To Jake Locker, about to execute a play action fake, this must seem like classic Cover 2 zone, safeties high.
Here's the snap from a different angle. To note here is how Kyle Arrington has opened up. He is still outside the receiver, and he is facing the QB. Again, classic indication of zone coverage.
Here, mere moments after the snap, we see both Kyle Arrington and Tavon Wilson open their hips towards the QB and get depth. Neither is looking at anything resembling a wide receiver yet. Classic zone. Arrrington may seem to be in man due to his proximity to Nate Washington, but Tavon Wilson has long since left the slot man behind. Hightower (#54) is spreading out to the flats, and is giving that guy a solid jam.
Note Steve Gregory (#28), who is now briefly seen, as he is moving from the middle of the field towards the near sideline. What we are beginning to see here is movement towards a Cover 3 shell.
Trouble brewing. This is the time of Jake Locker's pump fake, whose effect is quite noticable when one studies the Patriots players in this image, all of whom have their eyes on him. Hightower and Spikes are collapsing from their zones on the slot receiver, while over top of him, Arrington is turning in to drive on Nate Washington, who is performing the stop part of the stop n' go.
Tavon Wilson, rookie fill-in, is mesmerized by it all and has stopped getting depth, quite sure the ball is about to be distributed somewhere in front of him.
Let us take a moment to reflect on the position of Wilson, Steve Gregory — barely visible beneath the ticker bottom right — and Kyle Arrington, who is practically on the sideline. This is Cover 3! If Arrington were in man he would be horrendously out of position that far off Washington and that close the sideline. Gregory is nearly on the numbers near side and is deep. Tavon Wilson is beyond 15 yards in the middle of the field. Perhaps, perhaps he is playing deep robber in a sort of Tampa 2. But then Arrington would still have no business being as far outside as he is.
One should also note how far outside the slot receiver Dont'a Hightower has spread. He began the play inside, went all the way to the receiver's outside, and is now collapsing in on the receiver, while Brandon Spikes (#55) drives from the inside. Again, clear indication of zone. Hightower has flats, Spikes has the far hash.
Here, frozen in compressed time and jpg, is Jake Locker's throwing of his first interception. Nothing else to see here apart from the two Titans just downfield, one of whom is Chris Johnson (#28), with not a Patriot player within five yards of them. You can barely make out the shadows of the slot receiver and Hightower off the upper right.
If this were man coverage, one or both of these Titans receivers would have been closely covered by a linebacker. Especially Johnson, who leaked from the backfield. So, again, this is zone coverage.
Jerod Mayo (#51) and Devin McCourty (#32) here make reappearences in the lower left. Mayo is quite obviously patrolling the near hash, and McCourty is in the near flat, each well away from the Titans we saw previously, who were close to the line of scrimmage. To belabor the point, this spacing is due to the fact that the Pats are in zone, not man.
Note that Kyle Arrington is recovering from his brief misstep, while Tavon Wilson intently stares down the QB.
Incidently, Jake Locker's snap read of Cover 2 is now made correct, thanks to Wilson's freezing on the pump.
This blurry action shot is either the most conclusive piece of evidence of the existence of Bigfoot, or that the Pats are playing Cover 3 zone here, or at least would be if Tavon Wilson had received the urgent memo, From: Kyle Arrington Re: Nate Washington Message Text: Hey guys, looking for inside help here.
This is what blown coverage looks like at 18 MPH. Tavon Wilson owes Kyle Arrington doughnuts all week for the butt-saving that's about to happen.
End.
