I think if any of the Dolphins' injured players are cleared by docs/trainers to play and the player themselves feels good to go, they go. This is a huge game for Miami as well. Aside from the possibility of the Bills being out with a loss, a win in this game means the exact same to both teams...the chance for 2 straight home playoff games, avoiding Baltimore until at least the AFCC game and possibly hosting the AGCC game if Bmore loses in Divisional.
I don't the Dolphins will, or should, rest anybody who CAN go.
