I would still go with Washington if you have them in standard leagues. Giants are locked into there spot no matter what, so would not be surprised for them to not give a shit at all.
Same line of thinking would caution against taking Pitt. They are locked, and although the browns probably blew their load last week, Pitt will likely be resting a lot of starters.
But in my other league I will be going with NE surely and agree they don't let it happen twice. Dolphins are locked into 6 seed and think they have already said they will be resting people.
