Optimizing Conference Scheduling for Tournament Selection: Part II, College Basketball

This is Part 2 of a two-part post about conference scheduling in college sports. I submitted a version of this for inclusion in this year's Evolution of Sport competition at the Sloan Sports Analytics Conference in March. Since they didn't accept it, I decided to post it here. Part 1 can be found here.

Since college football won't be very topical in March, I want to close this discussion with an example from college basketball. Now, the goal in college basketball is a 68-team, single elimination tournament. Of those 68 bids, 31 are reserved for the winners of the respective conference championships. The remaining 37 are handed out by a selection committee on the basis of body of work during the season. Since no one can watch every game, the committee gets some help by the Ratings Percentage Index, or RPI.
Now, again, the formula for the RPI isn't spelled out, and there are various bonuses for winning on the road and so on, but the RPI is estimated to be 50 percent strength of schedule. And wouldn't you know it: the RPI is very consistent from year-to-year, with a correlation coefficient of about 0.75.


What's at stake? Well, if you miss the NCAAs, there's always the NIT, and I've seen teams estimate that they can clear about $25,000 to $50,000 from a good NIT run. But make the NCAAs, and Forbes estimates that your conference gets just under $2 million per game to distribute to its members. Remember that year VCU went to the Final Four? That brought in a little under $9 million for the Colonial Athletic Association.

So yes, scheduling is very important in college basketball, and I've read articles that suggest the Missouri Valley Conference punishes members that schedule soft out-of-conference games that bring down their strength of schedule. But could they be doing more?

Here we have an example of another mid-major conference, the Atlantic 10, from the 2010-2011 season. The previous year, 5 of the A-10's 14 teams won at least 19 games. That's usually good enough to be a borderline tournament team, but the A-10 only got 3 bids. In 2010-2011, the A-10 had 6 teams with at least 23 wins. And they got ... the exact same number of bids, for the exact same teams. Here you can see their conference strength of schedule as compared to their previous season's performance, and no surprise: winning doesn't correlate with the next season's strength of schedule. Note that each team played 16 conference games: you play everyone once, and then three teams twice. For the record, the teams in gold made the NCAAs in 2011, and the teams in blue missed out.


But if we take last year's performance into account, we see a drastic improvement in the average opponent's ranking for each of the top six schools – over a 60% improvement, in fact. And again, with the exception of the outlier of Fordham, strength of schedule matches up better with last year's play all around. Now, this won't necessarily guarantee you more tournament bids, but it'll improve your rankings and your public perception, and that might just be enough to get you off that dreaded bubble.


Now obviously this is not a finished product. The calculations and the sample schedules I used were strictly back-of-the-envelope stuff: there's no accounting for home-field advantage, which could be useful, and I'm almost positive the results I generated aren't optimal. And I'll admit, this won't work for every conference. You'll notice I didn't include any of the Mountain West Conference teams because there's no wiggle room: there are nine teams in the conference in football, so every team plays every other team once. That's it.

But if you're the commissioner of a college sports conference – and, with all the turmoil lately, you might be one and just not know it yet – consider all your options before you set that schedule. Take a good long look at that filet mignon. And then take a good long look at those cheeseburgers.

Bracket Showdown, Day 10: [Title Vacated]

With Kentucky's dismantling of Kansas in last night's national championship game, the first ever Feats of Strength Bracket Showdown has come to an end*. A comical 28 entries correctly put Kentucky on the final line. As I said on Twitter last night, I have never seen more experts pick the same team to win a championship -- and be correct -- in a long time. Then again, maybe I just haven't been paying attention.

Anyway, the Aluminum Pole for best performance** goes to Jerry Palm at CBS Sports, who picked 3 of the Final Four, both finalists, and Kentucky to win for a total of 146 points.
Congrats, Jerry; you've earned this.

Bracket Showdown, Day 9: Domeward Bound

RISD alumna and mascot-bracketeer Ashley MacLure illustrates the Louisville-Kentucky matchup.


No one, they say, wants to hear about your fantasy sports teams or your bad gambling losses. At the risk of losing my one reader, then, I'll refrain from complaining about the Ohio State Buckeyes, who snatched defeat from the jaws of victory and cost me a shot at my bracket pool. Fortunately, I had the catharsis of the Bracket Showdown, so as the Buckeyes stood around bewildered on the Superdome floor, I grimly set to work tallying up the points from tonight's semifinals, drawing larger-than-usual X's through the incorrect predictions.

Let's move on, and see how our panel of experts fared in the Bracket Showdown. As usual, the rules of the showdown are here, and the updated scoreboard is here.

Bracket Showdown, Day 8: ...Step 3 = Kentucky.

After a weeklong vacation in Las Vegas, Bryan triumphantly returns to the blog with an update on the 36-entry Feats of Strength Bracket Showdown.

After two glorious weekends, four teams are headed to New Orleans to compete for the college basketball championship. Sixty-four other teams are not headed to New Orleans or, at least, if they are, will be mostly limited to drinking hurricanes on Bourbon Street. Let's look back at our Bracket Showdown and see how our contestants are doing. The full scoreboard is available in this Google Document.

Bracket Showdown, Day 2: Where the hell is Lehigh anyway?


"Sir, the possibility of St. Bonaventure winning the tournament is approximately 3750 to one!"

The first round of the tournament is in the books, and my bracket is in enough disarray that I can stop worrying about winning my office pool (which was never going to happen anyway) and start rooting for chaos. Let's go Mountain Hawks!

Anyway, let's check in on our team of experts and computer simulations and see how they're doing:

Bracket Showdown, Day 1: Barack, Chalk, Jayhawk

The greatest first day of the tournament I ever had was back in 2008. Between a series of brilliant thefts of other people's deductions and some good old-fashioned dumb luck, I actually got all 16 games correct. Like a pitcher in the middle of a perfect game, I refused to talk about it, but spent a good part of the morning going back to ESPN's bracket challenge page to admire the score.

It wasn't long, of course, before I got my first loss of the tournament. It was all downhill from there, and I finished somewhere between "mediocre" and "flipping coins" that year.

All of which to say that March Madness is not a mad dash, but rather some kind of mad marathon*. Still, it's never to early to jump to conclusions! Let's take a look at the scoreboard and discuss the results of day one:

Bracket Showdown: Just the FAQs, Ma'am

As the NCAA college basketball championship gets underway, The Feats of Strength will be hosting a showdown between dozens of brackets from college basketball experts, analysts, celebrities and more. Winner gets an aluminum pole -- very high strength-to-weight ratio*.

"No decorations. I find tinsel distracting."

Today, I explain the rules of the contest. What better way to do that than the ol' Frequently Asked Questions gimmick? Well, except that no one's reading this blog, let alone asking questions, so let's call it the "Fruitlessly Anticipated Questions" section.

Announcing the Feats of Strength Bracket Showdown!

The header on this blog might lead you to believe that actual analytics will show up on this blog someday. For a variety of reasons, that day is not today, and it's probably not tomorrow, either. As a cop-out, I'm taking a page out of junior high science fairs everywhere and seeing which laundry detergent works best* whose March Madness bracket predictions are best.

I've compiled 34 36 brackets from four categories: experts, celebrities, analytical systems and simulations, and a miscellaneous group of controls. The current list is below the jump.

Not all brackets are currently available. As the missing brackets get uploaded, I will paste in the links here.

Details about the scoring system will be posted tomorrow. Check back after each round for an update and see who wins!

Now, I know what you're saying, O reader, because I've hacked into your computer and have a live feed coming from your camera. You're saying, "Wait, what the hell?", but before that, you were saying, "This isn't very scientific! What good is a sample size of one?" And that's true. But like I said, this is more fun than anything else. Everyone makes these predictions every year, and wouldn't it at least be nice to go into next March knowing who did the best last year? Nevertheless, Operation Frantic Googling may yet reveal some past predictions to add to our sample. Rest assured, we have our top men working on it.


"Who?" "Top. Men."

Thinking Out Loud: Point-Shaving Detection

Those knee-deep in the hoopla of NCAA conference championship tournaments might not have noticed, but Yahoo! Sports reported yesterday that Auburn guard Varez Ward was being investigated by the FBI for point shaving. Auburn, that upstanding institution of higher learning whose athletics program has always followed the straight and narrow before, joins an august group including Boston College, Northwestern, and (my alma mater) Tulane.
