Not every book appears to be the same, as some favor the Texans by just 1 point, but others are giving them 3 points. The over-under point total is set at 46 points. The 2-0 Texans are averaging 28.5 points per game, while Denver is averaging 26. Houston's backfield of Arian Foster and Ben Tate give the Texans the sixth-ranked rushing offense.
While those numbers don't seem to match up with the over-under, it is defense that is dictating that line. While Denver ranks a respectable eighth in total defense, Houston is the best in the league, giving up a stifling 196 yards per game on the young season.
