I don't think that this would help at all.  These examples serve to set the 
stage for the rest of the proposal.  If you give Nascar (a sport performed by 
teams of athletes involving a driver and several pit crew) as an example of an 
individual sport, then readers will either be confused or think that you don't 
know what you are talking about.  If you give tennis as an individual sport 
then readers will have problems determining how to categorize doubles tennis. 
  If you give Snowboarding as an Olympic sport then those who realize that 
Snowboarding is instead an Olympic discipline either think that there is 
something tricky going on or think that you don't know what you are doing.  As 
so on.  You need instead to provide correct, and non-controversial examples.

That would help a bit, but the Wikipedia page is actually quite coy about not 
really defining what a sport is or is not.  It does more or less indicate that 
chess is not a sport, but it doesn't say just what a sport is.  It would be 
better, I think to state whether you believe that sports can have sub-sports.

Some of this can perhaps best be handled by saying that the result of a 
sporting event is a partial pre-order of the participants, plus some status 
flags.  Perhaps even better would be to distinguish between sports events that 
provide such an ordering and sports events that provide symbolic results.  Of 
course, some sports events might be both.

The actual details of decisions seems to be rather complex.  This is not 
helped by using PlaceDecision as that is used in several kinds of racing (win, 
show, place).  What is the difference between two competitors sharing a 
WinDecision and them both having separate WinDecisions?  Can a SportsEvent 
have more than one value for resultDecision?  Can you provide any example 
where this complexity matters?  If not, then why have the complexity?

Well if you want to model Cricket and Baseball, you probably need to do 
something along these lines.

I would suggest that you need to model the common situations, and seasons and 
competitions are very commmon.

A sports season has different structure than a list.  It may have a preseason, 
a regular season, and a post-season.  It may have several formal competitions 
within it that share sports events.  For professional sports leagues, 
complicated seasons are probably more common than simple seasons.  Even simple 
seasons aren't lists.  First of all, sports events are not text.

PS: I'm not sure how ItemList can be used to model the ordered list of Top 10 
Movies About Weathermen.  Can anyone enlighten me here?
