I seee it this way:
1. Bills win the coin toss - defer.
2. Houston first drive: 85 yds, 8 plays, TD; 7-0
3. Bills get ball - 3 and out. Punt.
4. Houston second drive: 65 yds, 5 plays, TD; 14-0
5. Bills get ball - drive 50yds or so, get FG; 14 - 3
6. Houston gets the ball - drive 80 yds, 4 plays, TD; 21-3
7. Bills get ball - INT or fumble; Houston goes 40yds or so after turnover in about 2 plays for TD; 28 - 3
Halftime.
etc, etc., etc., etc.
Final Score: Bills 13 Texans 55. Texans set Franchise record with 770yds total offense and not punting the entire game.
