An analysis of the Performance of TDS Athletic teams


I have been pretty active with both THS and BHHS over the past several years, and have observed hundreds of athletic events.  My overall impression is that THS, and to a lesser degree, BHHS, do not find adequate competition in the EVCO.  I wanted to collect some data, and see if my impressions were supported by the statistics.  Accordingly, I collected the EVCO results for THS and BHHS over the past 3 years(since the last classification was done).  Please note that this analysis only includes EVCO games, and does not include non-league games. 


 THS and BHHS are both classified as 2A schools and compete in the Evergreen Conference.  The other 4 schools in the Conference are Aberdeen, Centralia, Rochester and WF West.  Here is the enrollment over the past 3 years for the EVCO schools.  


THS has over 200 more students than its nearest peer in the EVCO.  BHHS sits in the middle of pack in 2A, and is about 80 students short of the EVCO average.  


The short answer is exceedingly well.  If things were totally balanced in a 6 team conference, one would expect each school to win about one-sixth(17%) of the conference championships. Things are not balanced in the EVCO.  Over the past 3 years, BHHS won 11 of 56(19%) conference championships across all sports.  However, THS won 24 of the 56(almost 43%) EVCO titles. As a result, the two TSD schools captured 35 of the 56 conference titles(62%), leaving the other 4 schools to split the remaining 21 titles(an average of about 5 a piece).  Here is the chart of the results in all sports for THS and BHHS for the last 3 full years(highlighted years indicate conference championships):


On average, BHHS teams win about 56% of their games.   More than expected, but not totally out of the norm.  A 56% win percentage is evidence that while BHHS excels, it is probably getting good competition the majority of the time.  

In contrast THS teams win about 74% of their games, which is much more than expected, and, in my view, indicates an inappropriate level of competition.  A 74% victory rate is indicative of a lack of competition, which, in my experience is pretty common with THS.  Notably, The 74% victory rate includes one team that only wins 5% of its games.  If that team was not part of the calculation, the winning percentage would be around 77%.  

15 of 19 THS teams win more than 70% of their games.  Astonishingly, 6 THS teams win at least 90% of their games.  I know that some of the readers will point to the THS football team, which has been dominant for years.   My personal view is that program is an outlier, and would likely be just as dominant in pretty much any league classification in the state.  However, it is somewhat surprising that teams can exhibit dominance in the manner in which the THS soccer, volleyball, cross country and track teams clearly overmatch their EVCO opponents to a point wherein the results are rarely in doubt before the games commence.    


THS has about 20% more students than any other EVCO school, and nearly 350 more students than the average of the other EVCO schools(without THS the average enrollment of EVCO schools is about 892).  The bigger pool from which to compile teams invariably results in more students with talent.   

Similarly, as I will outline in an upcoming blog, THS teams are comprised of a disproportionate amount of out district students, and it is clear that athletes transfer into THS in numbers that are even greater than the already disproportionate amount of the general population.  There are other variables which I have not mentioned.  These could include THS being a preferred location for coaches and boosters, facilities, and proximity to a larger population area(which may avail itself to more resources.)  I am sure there are other reasons which I have not contemplated.

WIAA is reclassifying schools, and the re-classifications will be effective for the 2020/21 schools year.  In my next blog, I will look at how WIAA classifies schools, and how the re-classifications may affect THS and BHHS.
