This game means a lot more to the Cowboys than the 49ers. San Francisco isn't going to catch the Rams (last two weeks Rams: at home Indy, Atlanta; 49ers: at Dallas, at NO) so that puts SF playing in the Wild Card weekend. Add the cold weather factor and I see SF resting a banged up Garcia and Co. in the second half. SF needs the win to keep the wild card game in SF (they could go to GB if they're not careful) but will they worry about a late score from Dallas? Probably not, so laying 6.5 looks a little dangerous to me.
