Contenders vs. Pretenders?

The San Francisco 49ers have a big game this week. The Niners take on longtime rivals in the Dallas Cowboys.

The rivalry dates back to at least the 1970s, but the Niners have had a decided edge of late. The edge revolves around the 49ers being a better ran organization.

Will the Niners prove the Cowboys to be pretenders on Sunday or will Dallas get its first big win of the year?
