They lost those four SuperBowls. Maybe they should have played to win those games.
I know that is facetious.
There is no right answer. If you play to win and someone gets injured then it was the wrong decision. If you rest everyone and lose the first game it was the wrong decision. In general I used to believe you rest people. The more I manage people, I do think there is a real issue of dialing down and turning up the intensity and disrupting the normal routine.
