I think the Titans have a huge edge in this game with being able to run the ball. Packers have struggled to run the ball this season and they are going against the best run stopping defense in the league in this matchup. This tells me they are going to have to rely on Rodgers throwing the ball. Normally that's what you would want but I don't think with a win over the Cowboys the Packers have figured everything out on offense. Titans are the more consistent team and have the running edge. I understand why some sharp bettors will be all over GB in this game and why they don't trust the Titans. But the matchup advantage is too great for me to overlook.
My pick for this game: TEN +3 (or better)
