2014 Gus Rankings: Gus ++ Week 13

Here are this week's Gus Rankings as we press towards the end of the year.  Marshall #1?  Of course!  6-5 Texas at #7? WHY NOT.

After the regular season concludes I'll give a fuller rundown of what this year's rankings experiment showed and set up its predictions for the postseason.  Who knows-- maybe we're on to something!

2014 Gus Rankings: Gus++ Week 10

This year's Gus Rankings have been nothing if not unique.  Nebraska has re-ascended to the top spot after Marshall's bye week; the Herd are second, followed by Alabama, Notre Dame and Mississippi State.

On the other end of the spectrum, New Mexico State finds itself in the final spot with a two point edge over North Texas.

But the fun doesn't end there!

Highest ranked team with a losing record: Arkansas at #33

Lowest ranked team with a winning record: Texas State at #114

There are only two teams without a win this year-- and neither are within 10 spots of the final position.

You can find this week's rankings here.  Also, don't forget to boycott American women.

2014 Gus Rankings: Gus++ Week 8

This year's Gus Rankings have been nothing if not interesting!  The partial wins experiment continues to produce interesting rankings; if nothing else, teams seem to have a bit more inertia than last year.  Large movements-- even after previously-understood significant wins or losses-- do not seem to be the norm this year.

You can see the latest rankings here.

2014 Gus Rankings: Gus++ Week 6

After a tumultuous weekend of college football, Gus has chimed in!  Notre Dame sits atop the rankings again this week, followed by Nebraska, Alabama, Oklahoma and Auburn.  And while there may be few certain things in life, UMass at the bottom of the rankings is getting about as close as it gets.  The Minutemen get their chance at a fellow winless squad in Kent State this week-- which, by the way, Gus likes more than 3-2 Louisiana-Monroe.

The surprise team of the week?  The Thundering Herd of Marshall sliding in at #6!

2014 Gus Rankings: Gus++ Week 5

Our apologies for the two weeks' break!  We're back at it and all formula'd up.

One quick note-- I neglected to mention a new part of the rankings.  We've added in a strength of opponents measure as well.  Basically, without the details, teams receive more points from defeating teams that play stronger schedules and lose less points from these same teams (and vice versa).  If there's sufficient demand for the details, I'd be happy to lay it out for all to see.  Again, as we go through the season it should be interesting to see how it all shakes out.  And if anything emerges as a shortcoming...that goes on the list for next year's improvements!

Without further ado, here are this week's rankings.  Notre Dame finds itself atop the list, followed by Oklahoma, Nebraska, Alabama and Mississippi.  On the other end of the spectrum, Massachusetts has staked itself to a strong lead for the title of worst team in America.

2014 Gus Rankings: Introducing Gus++ and Week 2 Rankings

College football season is upon us, and that means Year 6 of the Gus Rankings!  As we did last year, we've added a new wrinkle to the calculations this year to try and better capture the nature of game outcomes.  The goal is to try to build a ranking system from the ground up that is as objective and as transparent as possible.

Last year, we considered the margin of victory when determining the points that teams get from games.  Instead of having a last second field goal swing a team from a win (and the points generated from a win) to a loss (and the points subtracted from a loss), we generated an algorithm that translated a final point differential into a fraction of a win and a fraction of a loss.  (It was at this point that you fell in love with the inverse hyperbolic sine function.)  Does it perfectly capture the dynamics of a game?  No; we aren't ever going to be able to capture all of the nuances of a game down to a single number.  But it was a step in the right direction.  Also, overtime games were also viewed as a 50% win and a 50% loss-- why judge some games by more than sixty minutes and others by sixty minutes exactly?  We kept everything the same outside of that from the original rankings-- and so that was Gus+.

This year's adjustment corrects for what I consider to be an oversight of last year's system.  At the base of the original Gus Rankings was the idea that you gain points equal to the number of wins the teams you defeated had, and lost points equal to the number of losses of the teams that defeated you.  That never changed.  What changed was that you now didn't always get the entirety of your opponent's win total if you defeated them; if the score was sufficiently close, then you only got a fraction of the win total or loss total.  This year, we're keeping track of the effective wins and effective losses that a team accrues throughout the year.  So underneath every team's reported, on-the-stadium-program record is their effective record-- the sum of the partial wins and losses that they accumulate throughout the year.  It is from your opponents' effective wins and effective losses by which you now gain or lose points.  It's called Gus++.  If you like the name, thanks!  If you don't, it was Rob Holub's idea.

A note of thanks goes out to my graduate assistant, Kevin Gormley, for wrangling a lot of this together into a workable spreadsheet.  We're fairly certain the wrinkles have been ironed out; once we are good on that margin, we'd like to be able to report all three iterations of Gus Rankings for comparison and, you know, because data.  Onwards and upwards!  Comments, complaints, grievances, etc. are welcomed as always.

Without further ado, here are this week's Gus++ Rankings.  Oklahoma nabs the top spot; UMass stakes itself to the early "lead" for the worst team in the country.  Interesting results throughout!

2013 Gus Rankings: Gus+ Week 15

Here are the final regular season Gus+ Rankings.  (Army/Navy still needs to be added after they play on Saturday.)

If Gus were determining BCS pairings, conference champions remained and selections were made based upon the final Gus Rankings:

National Championship Game: Florida State vs. Stanford
Rose Bowl: Michigan State vs. Ohio State
Orange Bowl: Missouri vs. Arizona State
Sugar Bowl: Auburn vs. Oklahoma State
Fiesta Bowl: Baylor vs. Central Florida

And, as expected, Miami (OH) runs away with the worst team in America award by nearly 11 points.

Worst Gus team to make a bowl game?  Colorado State at #88.
