College Homecourts (2/16/12)

Today's blog will revisit college basketball homecourt advantages.

College Basketball Homecourt Advantage:
A few weeks ago, we discussed our modifications of college basketball homecourt advantage, including a ranking of all 345 Division I homecourts. It may have been lost in the previous blog entry and deserves more focus. Plus, as part of some other engine tweaks we rolled out last week (more on that next week), we made some slight revisions to our homecourt advantage approach. And, logically, some of the numbers have changed over the last several weeks of games.

Homecourt advantage in college basketball is typically presumed to mean "about four points" (the average right now is actually closer to 3.7) difference in the final score. This means that if two teams were identical, neither team would be favored on a neutral court and the home team would be favored by about four if they played at one of the team's arenas. This can lead to essentially an eight point swing from one venue to the next. The truth is that some venues could actually mean up 10-11 points, while some do not help at all (and there are 345 DI college basketball arenas). Our historical accuracy in college basketball during preseason tournaments, conference tournaments and the NCAA tournament is greater than 60% ATS. However, in regular season games (i.e. where one team plays on its homecourt as opposed to the games being played on neutral courts), our performance has not nearly been as strong.

In addition to the obvious difference in our performance, tracking line movements in the Play Analyzer prior to our initial improvements to unique homecourt advantages noted lines played at the same arenas typically moved in the same direction. As we researched this further, it became clear that, aside from injuries or late-breaking roster information, line movements most often moved in the direction of homecourt (favoring a team with a strong homecourt by more or favoring the away team by more when the homecourt is not as strong). As generalized as I can state it, if the consensus for books is to flatly apply four points for the home team, those who understand the true application of home court advantages exploit that and, in turn, move the line. I do not mean to speak for books or even to say that blindly following this strategy will yield profitable results, but it did lead to some significant changes on our end as we better account for each venue's true value (relative to pace of play) both for the expectation in the game being played and in how to remove the bias of homecourt in a team's data. We have always done this to some degree, yet have drastically improved this process.

The updated chart below ranks every DI college basketball team in order of the strength of its homecourt (as ranked by expected points per possession that the homecourt adds). Sorry fans, it seems as though homecourt advantage is most closely tied to things beyond your control (at best, fan impact can be tied to free-throw percentage against, but I do not subscribe to that theory enough, nor is there enough of a statistical case to incorporate free-throw percentage against). Strong homecourts seem to fall into one of three categories: 1) High elevation (the top four arenas and six of the top eight are all at least 4,500 feet above sea level), 2) Extreme tempo teams (teams are more comfortable dictating tempo at home so the fast teams like Missouri tend to play their fastest and the slow teams like Wisconsin tend to play their slowest at home) and 3) Average conference teams that still draw sizable crowds (terrible teams are terrible anywhere and great teams are usually great anywhere, but average teams with a strong fanbase, like Oklahoma State, Alabama and Toledo have very good homecourt advantages). Remember that homecourt advantage compares expected scores at home AND on the road to quantify the value of playing at home.

In the chart, have included the raw, historical point values that we have calculated each of the 345 DI venues to warrant for home basketball games. Remember that the actual ranking is pace-adjusted. All data goes back to 2000. For teams that have new arenas, seasons in new arenas are given stronger consideration.

The Predictalator

The Predictalator is the most advanced sports forecasting software available today because it has the ability to account for all of the relevant statistical interactions of the players (playing or not playing/injured), coaches, officials, fans (home field advantage) and weather in each game.

04/14/2014 Highlight: Using the ResultsFinder for the week of April 7th - 13th, one could find that all highlighted, MLB "normal" or better picks went 26-19 (58% ML, O/U, RL). This includes "normal" over/under picks going 10-4 (71% O/U). All-time (since the start of the 2012 season), all normal over/under MLB plays are 270-212 (56% O/U).

As the regular season concludes, NBA plays are heating up. All normal plays for the week in the NBA went 7-4 (64% ATS & O/U). Total picks continue to be strong, going 4-2 (67% O/U) with "normal" picks last week. Such "normal" plays are 43-32 (57% O/U) since the beginning of the year in the NBA.

The Predictalator plays every game 50,000 times before it's actually played. This provides us the ability to assign probabilities to the likelihood of just about any outcome occurring in any contest including straight-up, against-the-spread and over/under winners of each game.
