Things to Note:
  • Remember the opening playoff game last year? Where Carolina unimpressively put the Cardinals' season out of its misery? To remind you, Arizona managed 1.8 yards per rush AND 1.8 yards per pass in that game. They had zero big plays. It was awful. They managed 16 points (mostly thanks to 3 Carolina turnovers) but they never looked in the game. Why am I bringing it up? Houston managed a worse game score in their game this season. Their offense also put up a worse DVOA rating than that Arizona offense did (-77% vs -75%). Yikes. 
  • Can't explain this: the best performance on 3rd down of the weekend belonged to the Houston Texans. 
  • Cincinnati is the lone team to emerge from their game with a positive game score but without a win. That is almost completely thanks to their better performance on 3rd downs. They performed worse than Pittsburgh in yards per play, toxic differential, and (obviously) points per drive, but they could have (and should have) won the game. 
  • The Vikings out-passed the Seahawks per play 6.1 to 5.5. This shows that Russell Wilson continued his career-long trend of being more affected by bad weather than his counterpart. 
  • Looking at the stats, Green Bay-Washington was a much closer game than the final score would indicate. In fact, the game essentially came down to red zone performance, as the Packers scored 4 touchdowns in 5 red zone attempts, while the Redskins were only 1-for-4. 
The Forumla: 
I have modified my formula from last season. The new formula is broken down into four parts: 

Part 1: Yards per play. 
Here I take each teams yards per carry (rushing) and yards per attempt (passing) numbers and subtract from them the YPC and YPA their defense allows.  The theory being that, if Team A's offense is better per play than what their opponent's offense can muster against Team A's defense, Team A should be consistently better than their opponents over a full game's worth of plays (60 to 70 per game approximately). 

This part of the formula is unchanged from last year's model. 

Part 2: Toxic Differential
A better yards per play differential is helpful to a team's chances of winning, but just how often is an NFL team able to consistently drive down the field taking 5-8 yards at a time? You're essentially asking an NFL offense to put together 10-12 plays without more than 1-2 negative plays, be they incompletions, sacks, no-gainers, or worse: turnovers. It's doable, but it's really hard to do with any sort of consistency in a single game.

This is why coaches harp on turnovers so much. A turnover a) takes away an opponent's possession which decreases their chances of scoring more points, and b) can give your team a shorter field so you don't have to put together an 80+ yard drive to get points of your own. The problem with turnovers is you can't count on them. So much of what goes into a turnover is dependent on a) the other team and b) luck that relying on turnovers is a dangerous proposition.

So yes, turnovers are important. But there's something else that can make getting points in a drive much easier: big plays. If my offense can get 20 or 30 yards in a single play, that cuts out 4-6 plays of grinding, or 4-6 plays where something could go wrong. Now my offense only has to put 5-6 plays together on a drive where they also get a chunk play.

Brian Billick is credited with coming up with the toxic differential statistic. This adds your takeaways and big plays generated by your offense and subtracts your giveaways and the big plays given up by your defense. Again, the theory goes that teams with a better toxic differential will be better at turning drives into points and games into wins. Pete Carroll also bases his offensive and defensive identity around turnovers and big plays being the most important indicators for both sides of the ball.

Note: For this formula, a big play is considered a rushing play of 10+ yards or a passing play of 25+ yards.

This part of the formula is from last year's model, but I weigh it differently in this year's model. Last year it functioned as an accumulative factor over the course of the season, I changed the weighing to have it function as a per game factor, to better match the other parts of the formula. 

Part 3: 3rd Down Efficiency
Here is the big difference between last year's formula and this year's. While turnovers and chunk plays make moving the ball down the field much easier, it is possible to crawl your way to points with long, sustained drives. However, you can't have a long, sustained drive without converting 3rd downs. If you're not hitting for explosive plays, you had better convert some 3rd downs, otherwise your drive will end in a punt, instead of points. 

This part of the formula is brand new to this year's model. 

Part 4: Points Per Drive
What's the most important job of an NFL team? Score more points than your opponent. Rather than look simple points per game differential, I wanted to dig a little deeper and normalize the data a little further. Game-to-game the number of possessions can vary based on team tempo, weather coniditons, etc. So instead I looked at points per drive data for each team's offense and defense, and multiplied the difference by 10. Why 10? A typical NFL game has 12 possessions, but 1-2 of those come at a point where a team isn't really interested in scoring (maybe they get the ball with 12 seconds to go before halftime, or they get it with 3 minutes to go in the game up 14+ points already. 10 seemed like a good number of possessions per game where the end goal is to score points.

This part of the formula is unchanged from last year's model.
