There is no chess game going on here. Both teams were put in a position to do what they had to do. The Eagles had to rest Hurts and play Minshew. Now they are in a must win situation so they will rush Hurts back onto the field. The Cowboys would probably prefer to rest some of their ailing plays, and in fact they are, but they also want to win because there is a chance the Eagles lose.
I don't think Dabol is worried about revenge or payback or anything like that right now. His team is the 6th seed in the playoffs no matter what. He wants to win his playoff game. This week the game means nothing to him and his team. I would not be surprised to see him play Jones and Barkley to start the game and pull them after the 1st quarter. He has other players he will rest as well. Beating the Eagles then losing his first game in the playoffs will get him nothing.
Even so, the Cowboys still have to play their game to win. Perhaps if the Eagles are winning 48-10 or something like that in the 4th quarters McCarthy can pull his starters and give the backups a chance to get some playing time.
I am pretty sure if McCarthy had his way he would prefer the Eagles to play at 1:00pm and the Cowboys to have a late game so he could rest his team if the Eagles were to win.
