That's the only reason I can think of why the over/under on this game is only 45. For the past 9 weeks Dallas has had their game totals go over 50, most of those being well over 55. And they are playing a team defense that somehow managed to give up 19 points to Carolina. Dallas' team total is 26. Wouldn't surprise me the least bit if they cover that early in the second quarter.
I know Arizona is not exactly known for its high-octane offense, but neither is Washington and Dallas still gave up 30 points last week.
