You brought up the Lions because they are the next Cowboys opponent, that has put up points so far in 2022.
Detroit has scored 140 points in the league this season - and have given up 170 - a differential of -30.
The two teams that have scored more points that the Lions - the Bills and the Chiefs - have point differentials of +94 and +31 respectively.
Both BUF and KC are on 2-game win streaks, are 4-1, and lead their division.
DET has lost 3 straight, 1-4 (only one of 5 teams with just one win so far) and are last in their division.
In summary ... I have more belief in the Cowboys exerting their defensive dominance over the Lions' offense... plus Dallas' so-far pedestrian offense to perform better against a bad Detroit defense -- be it Rush or Prescott as the starter.
