I don't really see the Miami game as a trap. 2 bad teams and the home team is usually favored by a field goal
One I think may be a trap that you didn't post is Baltimore against Detroit with Detroit at home -1. All the talk is about how bad Detroit is and how Harrington is a bust and can't make it in the NFL which is true, and on top of that how Baltimore has such a great defense. To me it looks like the books want you to take the great defense team against the horrible team PLUS get a +1. So I believe the smart bet would be on Detroit -1.
I may be completly wrong, but I would like your opinion on this since this trap system has been doing pretty good so far.
