The Chargers are at Oakland today, and in each of the last three years, the first meeting between these teams has been a lot higher scoring than the rematch. Is that just a coincidence? Or is it a trend that tends to be repeated with other teams?

We know that divisional games tend to be lower scoring. It’s usually about 3 points per game (about 1.5 points per team). Explanations vary, but I think it’s because defenses get a feel for what they need to do. They learn the personnel, develop some immunity to some of the go-to plays, and start to figure out what will be called in key situations.

If that’s the case (or the tendency) it stands to reason that when teams meet for a second time in the same season, it should be more of a benefit for the defenses.

So I checked the numbers from the last 10 years. And they do support the notion. Looking only at divisional games, there has been an average of 44.3 points scored in the first game between two teams in any given season. The total drops to 43.3 for the rematches – a point less per game.

This is based on 960 games – 480 two-game series. In 251 of those series, the first game featured more scoring. That’s 33 more than the rematches (218, with the remaining 11 series featuring the same score in both games).

In 157 of these series, one of the games featured at least 20 more points than the others. On those, 85 of the high-scoring games were in the initial matchup (versus just 72 in the rematch).

This is more of a tendency rather than a rule. We can’t look at any one series and promise the first game will be higher scorer. But as you look at many games, it’s more likely that the big, high-scoring shootout will come in the first meeting between two teams.

Since 2000, there have been 29 games between divisional foes that resulted in more than 75 total points being scored. Of those 16 were the initial meeting rather than the rematch. Again, not a hard-and-fast rule, but if you’re looking for more production, it’s more likely to come in the first game.

(In chart here, the rematch games include a black dot, and there are only 13 of them).
