Can the St. Louis Rams win their division?

Dec 2012
OK i know the 49ers have the better overall record in their division at 8-3-1 but their division record is 2-1-1, while the st Louis rams division record is 4-0-1 overall 5-6-1. If the rams remain unbeaten in their division shouldn't they be the division leader even if their overall record is not better than the 49ers?
