ANALYSIS: With a spread of this magnitude, don't blink and just go with the underdog. Forget Dallas' league-best points differential. Ignore that the Texans have a single straight-up win. If there is anything to hang one's hat on, Davis Mills returns as QB after a two-week absence. Of his 10 starts, Houston has not lost by more than this spread, though one defeat equaled it. The Cowboys have been explosively lately, but that isn't their M.O. historically under QB Dak Prescott.
