Merry Christmas
I don't like this trappy game. Dallas are out of the post-season and you may find Stephen McGee defending your lead in the fourth, so my last brussels sprout isn't going on the result (for the record though, Dallas should cover).
A better bet is Witten to score; Arizona struggle in coverage with average safety play and nicked up linebackers, so at Evens, Witten looks a nice price in a Dallas O that gives him lots of looks in the redzone.
Pick: Witten Anytime TD Evens 2pts (Sky Bet, Corals)
