Final 2008 NFL Standings with Victory Weighting

In Victory Weighting, teams are ranked by their Strength. If two teams have the same Strength, then the one with the higher overall winning percentage gets the higher rank.

With that in mind, let's see how the final 2008-9 NFL standings would have appeared under Victory Weighting. Playoff teams in these listings are preceded by their seed in parentheses.

Usually, Victory Weighting produces the same set of playoff teams as do traditional standings, but seed them differently. Here, Carolina would have earned the #1 NFC seed, and the Panthers would have hosted Philadelphia at the divisional playoff stage.  The New York Giants, the actual top seeds, would have fallen to #2, where they would have met surging Arizona.

Last season also provided a less common result:  it actually produced a different playoff field.  Miami completed its Cinderella run by winning the AFC East and hosting Baltimore in the wild-card round.  Under Victory Weighting, however, the Dolphins would have missed the playoffs altogether, and New England would have hosted the Ravens instead. The difference is that only the Patriots had a game go to overtime. The OT loss gave the Patriots an extra Strength point.

How To Improve NFL Overtime

Baseball resolves ties by playing full extra innings. In basketball, tied teams play extra time in 5-minute parcels. Even in soccer and hockey, they get it partly right, with fixed overtime periods preceding those dreaded shootouts. In none of these sports does the game stop at the first score. But in the NFL, overtime consists of a sudden-death period that ends the first time somebody scores. Sometimes, the result of an NFL overtime has some fairness. When both teams are allowed to possess the ball at least once, they can reasonably claim that the OT period tested all of one team against all of the other. (That's why OT works in those other sports.) Unfortunately, many NFL overtimes end after only one possession. When that happens, overtime tests only one of half of the winning team against half the losing team. Yet, the winning team still gets full credit for the win. That's wrong. College football teams use a different scheme, giving each team in a tie game an additional possession at the same place (usually the near 25-yard line). The team that scores more points in its possession wins the game. In case of tie, the teams get another possession and try again. That's more fair than sudden-death, but each team gets more than a couple of chances, it can occasionally take a while. Let's review: NFL overtime doesn't work fairly, but the best fix, the college OT scheme, takes too long for the NFL to implement. The good news is, I have a solution. Enter Victory Weighting. The basic idea is this:
The winner of an NFL game should get more credit if they do it in regulation.
If overtime is required, the winners shouldn't get full credit for the win. On the other hand, the loser of an overtime should get a little credit for forcing overtime in the first place. To enforce this principle, we just add another column to the standings. In addition to a won-loss record, each team receives a Strength score. Every game played adds up to four points to a team's Strength, based on how the team fared:
  • Regulation win: +4 Strength
  • Overtime win: +3 Strength
  • Tie: +2 Strength
  • Overtime loss: +1 Strength
  • Regulation win: 0 Strength
For example, as a result of last night's game, the Steelers now have a Strength of 3, while the Titans have Strength 1. Both team's Strengths have been weighted by the fact that their game required overtime. (Hence, the term Victory Weighting.) In most cases, the standings using Victory Weighting will be the same, but there will be deviations, especially during midseason, when some teams have taken their byes while others are still waiting for their weeks off. As we'll see next time, when we review the 2008-9 season, Victory Weighting can also impact playoff bids.

"Eat Yer Burritos," Take Two

Hi! "Take one" was something called "Shaddup and Eat Yet Burritos," which also lived on Blogspot. I had hoped it would be a general-purpose blog, but somehow, it turned instead into a football blog. That really wasn't what I wanted. At the beginning of this year, I had to turn my attention to more pressing matters, like moving halfway across North America. Of course, I could have just added new posts to the old blog, whose last entry was in January. On further review, however, I decided to move the blog to a new place. For one thing, it was inspired by the fact that I was living in Maricopa County, home of Sheriff Joe Arpaio and his anti-immigrant obsessions. While Illinois has plenty of immigrants, the obssession isn't as strong, so the title doesn't mean as much. More to the point, it occurred to me that I have something else to talk about in a blog. One of my favorite things about the 1970s was the CBS Radio Mystery Theater, the nine-year, 1400-episode extravaganza that marked the end of radio drama in the U.S. I have quite a few things to say about CBSRMT, enough for years' worth of weekly or bi-weekly posts. Hence: The Ghost-Grey Cat. The new title is a play on "The Ghost-Grey Bat," one of the best horror installments of the entire CBSRMT run. I'll discuss this episode, and CBSRMT in general, in the weeks to come. Meanwhile, the NFL season has started again, so I'll first talk about Victory Weighting, my proposal for making sudden-death overtime periods fairer to the teams that have to endure them. Happily, the Titans and Steelers gave me more material last night. Anyway, welcome to The Ghost-Grey Cat!
