Preseason Sunbelt Conference Football Coach Poll

Recently Florida International University was voted as the pre-season favorite for winning the Sunbelt conference in football this coming season.  Below are the coaches first place votes, and total votes from the pre-season poll.  Next to that are the wins and losses from last season (including any post-season bowl games).  Finally, the last three columns are the rankings (out of 120 NCAA FBS schools) in terms of the NCAA production model for the team's total production rank, offensive production rank and defensive production rank.  You will note that most teams in the Sunbelt Conference are ranked below average (higher than 60).

I think I will come back to this at the end of the season and see how well the coaches (and last years model's ranking) relate to the end of the 2012 season for the Sunbelt conference.

NHL Post-Season Goalie Evaluation for 2011-2012

Now that the NHL playoffs are over (congrats to the Los Angeles Kings), let's take a look at how the goalies performed during last season's playoffs.  I calculate goalies post-season performance in the same way as I have previously done, with the exception that I am calculate the coefficient on post-season goals against, instead of using the regular season in the Wins Above Average calculation.  Here are the results for the 2012 NHL playoffs.

NBA Attendance Analysis

One of the topics that I talk about in Sports Economics is the impact that a lockout has on attendance.  Obviously, with a lockout the total number of people that attend all league games for that season will fall as there are fewer number of total games played.  Yet that does not really get at the issue at hand.  So, one way to tackle this problem is to use intervention analysis.  In essence, intervention analysis is a time series statistical technique that examines how the average value of a series of numbers changes given a specific intervention.  Specifically, we looked at how the first difference in the average value of total league attendance changed due to a strike or a lockout, given that attendance is non-stationary over the time period that we were looking at. This is exactly what we did in chapter 2 of the Wages of Wins.

Unfortunately, at this point in time, I cannot first difference the attendance data for the current NBA season, since the next NBA season (2012-2013) has not been played yet.  Thus intervention analysis is not currently possible to analyze the impact of the NBA lockout.

So, using total league attendance does not help, since the number of games played is different, and it is too soon to use intervention analysis.  Is there any alternative way to figure this out?  Yes.  One is to perform a t-test on the means of attendance.  So, I downloaded the team-by-team attendance data from ESPN, and entered and sorted the data into Microsoft Excel, and then calculated a t-test on home team average attendance for the 2011-2012 and 2010-2011 NBA teams.  The result of the t-test was that team-by-team average home attendance was not significantly different over the two seasons.  In other words, statistically speaking there was not a great enough difference in the two data series to say that one is different from the other; and thus I would conclude that the NBA lockout did not have a statistically significant impact on average NBA team home attendance between those two seasons.

Alternatively, one could just plot the data over the last few seasons and look to see if there is any visual difference.  While this is not all that technical, it does give some additional evidence that fans did not respond much because of the NBA lockout.  Here is a line graph of average NBA home attendance over the last four NBA seasons.  The line in blue is the 2011-2012 lockout season.
