INFOGRAPHIC: Do mega regular-season games lead to Super Bowl wins?

The 8-1 Broncos and 9-0 Chiefs will meet Sunday in the biggest game of the regular season to date. By winning percentage, no game from here on out will top it. When these teams meet again in two weeks, the added loss for one of the teams (or the tie for both) will technically lower the combined winning percentage below this week’s .944 clip. And the only other one-loss team in the NFL – the 9-1 Seahawks – doesn’t play the Chiefs.

So there you have it. Biggest game of the year, by that metric.

It got us thinking about other games of the year from recent history. How good an indicator is this of success come playoff time? Take a look at this graphic of the last 10 years’ biggest games:

Some interesting highlights:

*Of the 20 teams involved, only three later went to the Super Bowl and only two (2003 Patriots, 2009 Saints) won it.

*One team didn’t even make the playoffs – the 2008 Jets, who entered the game 7-3, beat the 10-0 Titans to go to 8-3 and then still managed to lose four of their last five to finish 9-7.

*The magic number of points to score appears to be 38. The two Super Bowl-winning teams scored that many in these games in winning efforts.

*These games resulted in playoff rematches four times, and this will be the second time in which there will be a regular-season rematch yet to come. In 2011, the Packers and Lions met again in Week 17, with Green Bay winning. The 2010 Jets-Patriots clash on this list was the second meeting between the two that season.

*Not surprisingly, this isn’t Peyton Manning’s first rodeo here. He’s 1-1 in these games.

*Not surprisingly, Manning has been outdone in that regard by Tom Brady’s Patriots, who have factored in a whopping five of these games and are an astounding 4-1.

*Offense has seemed to be favored. Teams with the higher-scoring offense won eight of the 10 games. Teams with the better defense in terms of points against per game won just five. (There were three instances where one team was higher-rated in both, hence the odd math.) Also, the team whose starting quarterback ended the season with a higher passer rating is 9-1.

*Home-field advantage hasn’t been much of a factor. Home teams are just 6-4.

Between the experience of Manning, the slight edge to high-flying offenses and the home-field advantage in Denver, the Broncos seem to have the edge, however slight. Vegas thinks highly of Denver, as well – they’re 8-point faves.

Probably the most interesting takeaway is that only three of these 20 teams (all 7-3 or better at the time of the game) went on to the Super Bowl. Proceed with caution, Chiefs and Broncos fans.
