I'd go with Arizona.
The Pats are decent, but are vulnerable through the air and have no answer for good tight ends like Owen Daniels. Plus, the Texans do everything well. At least, well enough not to give up double digit points to opposing defenses yet this year. They don't turn the ball over much, and they're best in the league at avoiding sacks.
Wilson and the Seattle offense have been good lately, but the Texans are better.
