AccuScore numbers game: Moss makes huge difference

The Super Bowl in October? It sure seems that way as the 5-0 New England Patriots roll into Irving, Texas, to square off against the 5-0 Dallas Cowboys. This game has about as much hype as the Super Bowl but without the halftime show, thankfully. One can only withstand so many wardrobe malfunctions in one lifetime.

Never being one to miss out on a media frenzy, we here at AccuScore.com decided to fan the flames and take a deeper look at this game with the help of the AccuScore Super Computer. That's what we do. We're geeks. We like math.

Our baseline simulations give a slight edge to the Patriots in this game, with New England having a little more than a 53 percent chance of winning. Dallas should thank its lucky stars that this game is in Texas. Were this game being played in Foxboro, the odds dramatically swing in the Patriots' favor, with AccuScore data giving them a whopping 68 percent chance of winning.

There is no doubt the Patriots have been one of the more dominating teams of the past several years. But the acquisition of Randy Moss makes them even more dominating. AccuScore simulated this game 10,000 times without Moss. After analyzing the data, the results are shocking. The Patriots without Moss drop nearly 12 percent in winning probability for this game, from 53 percent to 41 percent. Tom Brady's effectiveness drops 20 percent. New England's third-down conversion rate drops 3 percent.

Extrapolated over the course of a full season, Moss alone accounts for at least two additional wins. That could mean the difference between home-field advantage and a week off in the playoffs or playing on wild-card weekend.

AccuScore expects the Patriots to come out with a heavy passing attack. We adjusted New England's play calling and found that by having the Patriots pass 70 percent of the time instead of a more balanced attack, the team's probability of winning rose nearly 8 percentage points. This is a similar game plan to what the Patriots employed last season in the playoffs to defeat the San Diego Chargers, whose defense was coached by none other than Wade Phillips, the Cowboys' current coach.

If Dallas employs the same pass-happy strategy, its probability of winning had almost no change according to the data, but its probability of costly turnovers did rise, suggesting that Dallas would be better off sticking with a more balanced attack.

Regardless of the outcome, Dallas will only get better as the season goes on. The addition of Tank Johnson in a few weeks will certainly help, but the return of Terry Glenn from an injury will have a big impact on an already potent Dallas offense.

If Glenn were playing in this game, it would account for slightly less than a 2 percentage point increase in winning probability. While seemingly insignificant, every edge helps and those 2 percentage points make this game nearly a coin toss. It's amazing what we can do with excessive amounts of caffeine in our system. With Owens, Crayton and Glenn on the field at the same time, you have a solid possession receiver in Owens and two sure-handed receivers capable of breaking long yardage after the catch in Glenn and Crayton. In three key losses for the Patriots in the 2006 regular season, teams were able to throw underneath the coverage and break through. Look for Dallas to try to exploit that in this game with Crayton and Owens running slant patterns across the middle and a heavy dose of passes to Marion Barber, all hoping to break short passes into long gains.

What does this all mean? Well, other than that the folks here at AccuScore have too much free time, it means that if the New England Patriots have a good game, they will probably win. Dallas, on the other hand, must play a near-perfect game to have a chance.

Don't forget that last season, the Indianapolis Colts were 9-0 when they two-stepped into Dallas. The Cowboys executed an almost-perfect game and handed the Colts their first loss. And while many question the Cowboys' record, saying they have not faced a team like the Patriots, New England has not faced a team like the Cowboys.
