Recent history shows no matter who wins between the St. Louis Rams and Dallas Cowboys on Sunday, it probably won't be a close game. In the past four meetings between the teams, the victor has won by 20 or more points with the winner posting a minimum of 30 points.

That trend will likely to come to an end at the Edward Jones Dome Sunday in what should be a closer matchup than last year's 31-7 Dallas triumph. But while this game should be closer, I'm going to stray from my preseason prediction of a Rams win and give the edge to the Cowboys, who are seeking their third consecutive victory over the Rams.

No matter who plays quarterback for the Rams, it won't make enough of a difference because neither Shaun Hill nor Austin Davis is going to help them stop the run. The Rams are allowing 171 yards per game on the ground through the first two weeks and Dallas running back DeMarco Murray leads the league in rushing with an average of 142.5 yards per game.

Murray has enjoyed even more recent success against the Rams, including a 253-yard outburst in 2011. That's ancient history, as this is a different Rams team, but he also had 175 yards against St. Louis last season. Missed tackles and poor run fits have been abundant and this is the best offensive line the Rams have faced this season to date.

Whether it's Hill or Davis, the Rams should score enough points to keep it close, but they won't be able to slow Murray and the Cowboys enough to get the win.

My prediction: Cowboys 26, Rams 20
