I'm very confident they beat Houston. The Cowboys know how to beat bad teams. The offense plays well against unorganized defenses. The Texans are giving up 27 points per game (22nd overall in yards given up). The 3-13 Giants beat them at home. Should be easy pickings for this week.
Never underestimate the importance of these types of games for JG, JJ, and the league. The Cowboys must remain relevant for as much of the season as possible (even if they are just average). Keeps people tuning in to the games, which is paramount to the league and JJ. The league's worst case scenario would be a string of losses that basically removes playoffs as legitimate possibility.
A 2-5 record heading into the bye would mean a mass exodus from watching the rest of the games this season. The officials will give the Cowboys the benefit of the doubt on 50/50 penalties against weaker opponents especially in critical situations. Gives people a reason to tune in.
