UNDER 47.5 CHI/DET
This is the very early Thursday game with a 12:30 EST start time. It's bad enough that they're playing on Thursday, but the fact that it's so early is another factor in the favor of a low scoring game. Last week Chicago had a 3.6 YPP average, against a terrible Bucs defense while playing at home. They only put up 21 points in the game due to terrible TO's in their own half by Tampa in the 2nd half. This team really struggled offensively. Now they go on the road, on a short week, and facing the #1 ranked Lions defense. Forte and the run game will be shut-down and it will probably be up to Cutler to move the chains. I expect a very vanilla gameplan for Chicago, as you just can't afford to let Cutler lose the game for you. As far as Detroit is concerned, they've failed to score a TD in two straight games now. This offense is very inefficient and highly reliant on two players: Tate and Johnson. Chicago doesn't have the corners to shut those guys down, but I'd expect consistent help over the top in this one. Regardless, points will be hard to come by in this game. My model has this one at 42 total points so there's a lot of value on the UNDER.
UNDER 39.5 SEA/SF
Two elite defenses and two offenses that have been pretty inefficient lately. Seattle without Harvin doesn't have many playmakers on the perimeter, and Lynch is dealing with a back injury. San Fran has been very inefficient all season long with Gore, Boldin, and Davis showing their age while Crabtree regressing greatly. I think both defenses will have a lot of success in this game. Remember, these rivals know each other very well, they are well equipped to stop the read-option that each team has a lot of success with typically, and both are treating this like a playoff game. My model has this one at 39 points, and though there isn't much pure 'value' per say, I believe we'll see a very low scoring game in this one.
Good Luck
