The Rams are not the lowly team they were when Dallas last played them in 2011. In fact, St. Louis finished with just one less victory than the Cowboys last season.
That being said, the Cowboys were favored in this game and should have won this game. Dallas has the edge in experience, the more dangerous offense and a defensive identity. The Rams have talent but just don't match up well with the Cowboys.
Dallas showed what its team looks like when the production meets the potential. The offense was balanced, and Tony Romo wasn't asked to do everything. Rod Marinelli's defensive line wreaked havoc, and the unit recorded a takeaway.
If a team wants to make the postseason, it has to win the games it's favored in. The Rams aren't pushovers, but the Cowboys (on paper) have a playoff-worthy team. St. Louis does not.
This is a game the Cowboys were supposed to and needed to win. They took care of business at home and will sit atop the NFC East this week for their efforts.
