I'm gonna finish this just as well.
.....
The Texans started to go with their prevent defense, rushing only four.
They were able to put pressure on Manning (as they had all game long);
however, Manning continued to find the spots in the zone quickly at the start of the drive.
He completed 6 straight passes, none longer than 8 yards.
Then, on first and ten, Quin nearly pulled in an INT as Nading pushed the RT into Manning, forcing a bad throw.
(I don't think it was Quin's fault for not securing the ball; Garcon just made a good play coming back to poke the ball out before Quin had the chance to tuck it away.)
On second down, Okoye and Mitchell both pushed the pocket well, forcing Manning to hurry an incompleted pass to the RB.
On third and ten, Pollard dropped a little too deep and allowed a 17-yd completion to Wayne (McCain released the vertical route to switch to the TE entering his outside zone.)
On first and ten, Mario and Okoye combined to put pressure on Manning forcing him to dump off the ball to the RB. Demeco timed it well and broke off the pass.
A quick pass to the RB who lined up near the side line gained 7 yds (Demeco in 5-under man coverage) on second down.
........
Then on third and 3 at the Texans 10, Manning threw a TD pass to Clark on a post route.
I had no idea what the Texans D was doing from the 5-2 zone (specifically Diles and Pollard).
The middle hole was Demeco's area; he took care of that.
The outside flat was Jackson's; he took care of that in staying with the outside receiver in his zone.
Diles lined up accross the Center and dropped to his spot in the curl.
Diles needed to trust Demeco to take care of the RB and minded his own zone.
If the Texans wanted Diles to play run first, then Pollard had to be aware of the TE from the start so Diles can help Demeco keying on the RB.
Instead, Pollard took a couple of shuffle steps to the outside and couldn't recover.
(A couple of backpedal steps here would have been better.)

It wasn't that big of a deal as the Texans still led 27-17 with just 3:49 to play.
