Most of the services are on the Dolphins tonight and I would lean this way too. The only crazy factor that points to Da Bears is that no team that played the Buffalo Bills the week before has covered the next week. Since the Dolphins played the Bills last week, they would be our go against team. Amazing that we are into week 14 and this streak is still going strong. However, I think it ends tonight.
Miami has given up an average of just less than 12 points per game at home. Since the Bears are no offensive powerhouse, I can't see them scoring much more than the average Miami allows. On the other side of the ball, the Dolphins score 28.5 points per game at home while the Bears give up an average of over 25 points on the road. Not good numbers if you are a Bears fan.
The Bears are only 5-16 ATS in December road games since 1992.
Miami is 15-5 ATS when playing their last game on the road over the past 3 years...8-1 ATS off a road loss. In addition, they are 5-1 ATS at home this year.
I will make a small wager on the Dolphins tonight.
Good luck!
