Week 1: Saturday Predictions


The first 10 or so games are under our belt, and now it's time to move on to the main course. Starting next week we'll be moving on to a full look at several key matchups, but as of right now there's not too much to say since all of our data is based on last year's standings. Most of these wouldn't be too competitive no matter which year they were played -- hello Kent State at Alabama -- but in a few other instances it'd be useful to have more info about this year's teams -- we're looking at you, Boise State versus Georgia.

Now, presented without further commentary, are the first batch of predictions for the 2011-2012 college football season.

The 2011-2012 Tempo-Free Gridiron

Normally around this time I'd be writing a post about the changes I've made to my system over the last year and how those will affect the rankings and predictions for the coming year. I say "normally" because even though I've done that periodically over the last two years, generally the TFG predictor has done well enough to stay just ahead of Eddie's RBA system. With success comes a degree of complacency, but that complacency has allowed me to go through and automate a lot of the day-to-day running of the blog by generating the predictions, rankings, and projections, and uploading that to the blog for the final tweaks.

Besides, it's fun to watch Eddie fume and rage about trying to wipe the grin off my face.

Instead during the off-season I spent most of my efforts trying to support the massive amount of content we're planning to churn out this coming season. A basic overhaul of the blog, better weekly projections, more informative rankings, complete per-conference projections, integration with our Twitter feed, improved game selection for our not one but two pick'ems (both for TotalFark members and for the public at large), an upcoming countdown of the best BCS champions of the last decade, a regular look at the remaining undefeated teams (as opposed to the occasional glance last year), and more behind-the-scenes work on making it easier for us to get this information to you.

So while I've been busy contributing to the common good here, Eddie's been focused on himself and flailing around trying to catch up to me. I'm not worried just yet, and probably won't be until near the end of the year. After all, last year he started out strong, only to flag down the home stretch.

Maybe in the meantime I can start putting together predictions for that other football league.

Week 1: Mid-Week Predictions


So here we are with the first predictions of the new football season. Just a reminder that all the rankings here are the same as they were at the end of last year; they'll slowly start to adjust as our computers get data from this year. Given that, it's a little difficult to predict this first week or so, but we're still putting it out there. Also remember that we only examine games between two Division I (FBS) schools, so when Powerhouse U. plays Sister Mary's School of the Blind, that won't show up here, either. It's almost as if many of the big schools don't want to risk losing to a middle-tier out-of-conference opponent. Weird, right?

The 2011-2012 Regression Based Analysis

I really want to beat Justin. Not just "sort of" beat Justin. I want to wipe that ACC smirk of his face and really give him the business.

The bad news is that RBA is up to 73.2% accuracy since 2000 while TFG is at 74.0%, implying that Justin gets approximately 5.3 games per year more than I do. However, I have been making significant strides on the difference between expected accuracy and actual accuracy. As of today, the difference between my predicted and actual performance is down to 0.2%, meaning that I miss 1.3 games per year more than I think I should. This manifests itself as an improvement in the confidence metric, implying that I may yet beat him in the TFD pick 'em pool.

The major update to RBA comes in the form of conference versus non-conference home field advantage. Teams that play each other every year are less phased by harsh environments, whereas teams that infrequently travel into opposing stadiums are more rattled. Based upon my data since 2000, home field advantage is worth approximately 1.9 PPH in conference games. In contrast, home field advantage is worth 3.6 PPH in non-conference games.

I experimented with a lot of different home field advantage metrics throughout the summer, including per-team advantage, linear regressions by strength, and linear regression by strength difference. These features generally caused drops by 1% accuracy or more. Justin suggests that attendance makes a difference, but I don't have a way to get these numbers into the algorithm.

One of the ideas that Justin and I have thrown around is changing predictors when we detect a lot of mispredictions. I took a shot at this by pruning history when encountering N consecutive mispredictions and had very poor results. In general, I don't tend to miss many consecutive picks. Furthermore, by time we detect the change (presumably due to injury, suspension, or whatever), the change has corrected itself, meaning that we miss even more games later.

In summary, there have been major experiments but only minor tweaks in the RBA algorithm during the summer of 2011. However, I'm relatively confident that RBA will keep it close during the 2nd Annual TFD College Football Pick 'Em.

Welcome to the 2011-2012 season

Welcome to the 2011-2012 college football season!

After a lengthy slumber the Tempo-Free Gridiron is back for the new year, and the theme of this year is "More Content." Our goal for this year is provide you with more interesting and more frequent updates to keep you coming back for more. In addition to a new look, we've got a slew of new regular features for our readers throughout the year. These include:

  • Tuesday Trivia. Each Tuesday in September will explore a random trivia topic. We've done this before, but now we're making it official.
  • Undefeated Countdown. We did this last year in a somewhat ad-hoc manner, but this year we're doing it every other Thursday starting in October. We'll examine the remaining undefeated teams, their possible road to a perfect season, and the main obstacles in their way.
  • Conference Projections. Starting in October we'll have a weekly breakdown of the 12 conferences, spread out over three days. These breakdowns will include both the current standings and the projected final standings. The schedule will be:
    • Tuesday: ACC, Big East, Conference USA, Independents
    • Wednesday: Big Ten, Big XII, Mid-Atlantic, Mountain West
    • Thursday: SEC, Pac-12, Sun Belt, WAC
  • Games of the Week. Along with weekly predictions we'll focus on specific Saturday games that are interesting in some way or another. These may be the top-billed games on ESPN that week, or they may be a showdown of two middle-of-the-pack teams that pit an explosive offense against an impressive defense -- the Unstoppable Force/Immovable Object (UFIO) game -- or simply the game that's expected to turn into a shootout.
This is all on top of our weekly predictions, discussions, rankings, and complete bowl coverage that we've provided the previous years. Keep an eye on the blog or follow us on Twitter.

Revisiting Northwestern

Long-time readers may remember my claim that Northwestern was the luckiest team over the last decade. Well, now I get some validation from an independent source. The Iowa-centric blog Black Heart Gold Pants published an article today highlighting the luck of Big Ten teams since 2002. It's a great article, and I highly recommend reading the whole thing. However, one particular quote stood out to me:
In every year included in this study, Northwestern had a positive overall pythagorean margin, and in all but one the LOLcats had a positive margin in conference play. Their gigantic lead in the chart above isn't due to one season; it's consistently winning a game to a game and a half more than expected. Northwestern's nine seasons are all within the top 30 overall (eight are within the top 20), and all but 2002's 1-7 Big Ten mark are within the top 22 in conference play. Once may be a random occurrence, and twice a coincidence, but if three is a trend, nine is gospel. Northwestern wins close games.
Clearly, Northwestern continues to exceed expectations, despite its academic pedigree and talent gap.

The Big East: Great NCAA Tournament Disappointment, or Greatest Disappointment?


There's been a lot of noise in the sports media about the Big East and their record number of bids to the NCAA tournament. A week ago, the chatter was all about how dominant the Big East was this year and how they truly deserved the unprecedented eleven bids earned by teams from Division I-A's largest conference. There were some naysayers, of course, but they were generally at the margins of the discussion. Each of the teams have proven themselves during the grueling Big East schedule. It used to be that if you finished at or above .500 in the ACC, you had a guaranteed bid to the tournament; this year, if you broke even or better in the Big East, you were in.

On paper, the Big East looked dominant: nine of the top 24 seeds were Big East teams. Going by the chalk these teams would make it to the round of 32, with 9-seed Villanova likely to pull an upset over 8-seed George Mason. Even 11-seed Marquette -- pitted against 6-seed Xavier, and having just defeated eventual 5-seed West Virginia in the Big East tournament -- was an upset candidate. Big East supporters dreamed big. Eleven teams in the round of 32! An all-Big-East Final Four!

Sneak Peek: Game Predictions

Today's sneak peek gives you a preview of the new look and feel for our per-game predictions. There are a few changes to the table to better fit the look and feel of the new site and to convey the same info but with less information overload. Instead of listing the odds of victory next to each game, we're using a color-coding scheme where the likelihood of victory is related to the intensity of the background color.
