And while Dallas has taken care of business in the month of November with a four-game winning streak, cracks have started to show, as they eked out an OT win over Washington and a 1-point victory over Miami in the last two weeks.
Arizona, despite getting mediocre play from third-year QB John Skelton in relief of the injured Kevin Kolb, is playing their best football of the season, having won three of their last four games.
In four starts, Skelton has completed 50.4% of his passes for 750 yards, 4 TD's and 7 INT's. However, he still has WR Larry Fitzgerald, one of the NFL's most dangerous deep threats, and Dallas' secondary has struggled against similar big, physical WR's like Calvin Johnson and Brandon Marshall this season.
Third-year Ohio State RB Beanie Wells has carried the offense, setting the Cardinals franchise rushing record with 223 yards against St. Louis last weekend.
Defensively, Arizona hasn't done much this season, as they are ranked 25th in passing yards allowed and 20th in rushing yards allowed. Dallas native and former Texas Longhorn Sam Acho has stepped up in recent weeks, racking up 5 sacks and three forced fumbles.
If the Cowboys offense can click, there's little chance Arizona can survive a shoot-out, as the odds makers have set the line for Sunday's game at only 45.5 points.
