San Fran has been a little bit of a mess, but have not lost since their defeat at the hands of the Cardinals. The Rams seem to have lost all hope. They only have one sack on the season.
Clearly, it is better for the Cardinals if the Niners lose, but why else are you watching? The Cardinals have two games still against the Rams and one against San Fran to end the season.
Enjoy the game.
