Got to go with Miami in this one. The Jets just won big on the road and fish got blanked in New England...so Miami opens as a favorite when everyone 'knows' they have nothing to play for?
First, the fact that they have nothing to play for is a mis-conception. This is one of the last two stages this season for many of the players, INCLUDING Harrington, to prove they belong on A roster next season.
Second, a division rival likes nothing better than to ruin a rival's playoff hopes. The Dolphins and Jets do not like each other...they will not be going through the motions.
Third, Saban wants momentum for next year and will have his players giving all they got.
Miami -2.5 is my play today.
