Texans are a reasonable choice, but they have had 55 points scored on them after 2 games.
The 49'ers, 51.
The Chiefs, 62.
The Bills and Bucs, 26. Both defenses are regarded as strong. (The Bucs have scored 16 points)
I'm also impressed with the time-of-possession of the Bills in the 0-2 crowd. We're 1st.
