The Patriots' defense is putting up numbers not seen since the 2000 Ravens. I don't see the Texans, with their weak offensive line, lack of a ground attack and poor coaching, being able to solve New England's defense. 
New England is getting better offensively as more offensive linemen and wide receivers get healthy. The Texans have a slow, banged-up secondary and their pass rush took a massive hit with J.J. Watt sidelined for the season. 
Bill Belichick has had Bill O'Brien's number. The Patriots are 5-0 SU, 4-1 ATS versus the Texans since 2015. Belichick won't be adverse to running up a score, too. There is bad blood between these two teams after the Patriots filed tampering charges after the Texans tried to lure New England's director of player personnel, Nick Caserio, to be their general manager.
