because outside of america, the sports you mentioned are not huge in comparison in competitive regional events such as rugby, football, cricket,
i'll include all the Olympic events here in both World formats and Olympic format;
so swimming, cycling, running, etc etc.
for instance you hold a ''world series'' which is a very misleading name as there is no ''world'' involved in the series, thats like having the ''world cup'' compromised of only European teams, which is why again there is a separate competition comprised of only European teams.
the cricket while not embraced world over still includes more variety than the majority of sports in america.
i will use the football world cup as the best example as simply put it is the best example.
the teams went through a period of having 1-2 teams winning everything and this happens in all sports, you can go back to the Michael Jordan days to see this too in full swing, its just the way ''world'' events seem to work one region will have a better structure until another region shakes something up and hits a weak point and exploits it, or simply catches up.
going into a non-world event and back to football; the preimiership. now it had been Manchester Utd or chelsea for multiple years until other teams ''dynamics'' and various players matured came to fruition and are gelled properly, or have had their infrastructure and coaching styles catch up to the top teams alternatey AND in conjunction star players have retired and so have managers, for the past 3 years the tittle has been wide open, much like the world cup it is very tough now to predict a winner as teams are a lot closer.
brazil has won the world cup 5times, germany 3 or 4 i think but no one says ''omg they always win its boring'' because;
- we appreciate good play and amazing players
- whatever team wins is simply better and deserves it.
above all of this most of the world is used to seeing other nations win a lot more than others in certain sports, america for the most part has most big events just including american teams, the other ''big'' international events are not really big at all for people outside the americas.
