I would think winning the turnover battle would have a larger effect on wins & losses.
Aside from final score and TO’s, I would think TOP and penalties would be next in the pecking order of importance.
Here's a simple statistical analysis using a correlation coefficient (
r), which shows the relationship between winning percentage and a certain variable.
+1.000 = a perfect positive relationship
0.000 = no relationship
-1.0000 = a perfect negative relationship
The closer
r is to +1.000 or -1.000, the stronger the relationship. Values closer to 0.000 represent weaker relationships. Here are the
r values of a few variables for the 2018 season, ranked by their impact on winning percentage.
+0.613 Offensive Yards per Play
+0.606 Turnover Margin
+0.562 Offensive Yards per Game
+0.264 Time of Possession
+0.248 Offensive Red Zone Percentage
-0.075 Penalties
To eliminate confusion, I won't add defensive stats, but the penalties stat is what I was referring to earlier. It's a negative number, meaning that the lower the number of penalties, the higher the winning percentage. That makes logical sense. However, the
r value is so small that it's insignificant. The other variables listed all have a greater impact on winning percentage.
Looking at the numbers above explains why I said TOP and penalties don't really matter. They're not statistically significant when compared to other variables. Turnover margin matters. Offensive yards per game matters, but offensive yards per play matters more. That makes sense because high-tempo offenses can inflate their yards per game number by running more plays. Yards per play, on the other hand, gives an apples-to-apples comparison of offenses regardless of how many plays they run per game.
I'll poast my little head-to-head stats thing about a week before the game if people are still interested. It doesn't show this kind of stuff but it can still help you know what to expect. I've been compiling them for the last couple years to help my stress levels, lol. For example, if you see an opponent is really good at sacks, you don't freak out as much when an actual sack happens because you already knew that's something they do well. Sounds silly but it works for me.
