The chart, updated from the one published last week, shows how it can happen now that the San Francisco 49ers are 7-1. Everything that needs to happen appears realistic.
The 49ers will be favored at home against the New York Giants and Arizona Cardinals. The Seattle Seahawks will be underdogs against Baltimore and could be underdogs on the road against St. Louis. The Arizona Cardinals will be underdogs at Philadephia and San Francisco. The Rams will presumably be underdogs at Cleveland.
