I'm not that impressed with the Texans' Defense as the PR department is:
The only good (top-level) offense they have shut down was the Rams in week one, who they held to 14 points--but still lost. [Note, they did stifle the Ravens, but Lamar was out.]
They have given up 20 to Tampa Bay (a loss), 27 to Seattle (a loss), 17 (a loss), and 29 to Jacksonville (which they somehow won). That’s an average of 25+ in these four games against these three playoff teams.
Their average points allowed against the six playoff teams they have played is 22.5 points per game.
Further skewing their D stats, they have had the luxury of playing the Titans twice already, who have scored a grand total of 13 points in those two games. And, they held the Lamar-less Ravens to 10.
Yes, they are good. And mainly because of their defense, they have won 5 games. But the Defensive numbers are not as impressive when you look deeper.
Take the Over on 22.5 for the Bills' offense.
