I think the Cowboys are the most dominate team in the NFC but their what they lack on defense (is it really improving) shouldn't allow for "Patriot like" spreads. Hence, the Cowboys may not cover and the over on the total looks good against Detroit. I know Chance Harper thinks that Roy Williams being gone hurts the Lions offensively, but they still have enough talent (with Johnson, Mcdonald, Kitna and K. Jones) to score 21 and you know Dallas will score over 30. Look for Dallas to cover barely and watch out as the spread grows against Dallas' later oppenents.
