The St. Louis Rams are about as decent as a winless team has ever been, but they're going to run into some serious problems this weekend. The Dallas Cowboys are at home and in serious need of a win in the tight NFC East, a division where all four teams have underachieved to this point. Those who set the odds have not been kind to the Rams, and those who spend their money taking or betting against those odds are even more cruel.
Dallas opened as 10 1/2 point favorites, and that line has moved significantly. St. Louis are now anywhere between 12 1/2 and 14 1/2 point underdogs according to various oddsmakers. A two-touchdown loss seems a bit hard on the Rams, but it's unlikely (read: impossible) that they care about covering. They're just going to care about winning, and they'll struggle to do that this week.
