It is the same everywhere - endorsement/sponsorship earnings to prize money ratio. In tennis (2016) ,
Federer pulled in $60 million from sponsors and endorsement fees by Forbes’ count, along with $7.8 million in prize money. You can do the math !!
What math I see is:
Tennis player earns $7.8m from the sport
TT player earns $1.?m from the sport
So we talk TT
Could your national champion get lots of endorsement/sponsorship earnings? Because they can't really get a good salary from playing...
So lets look at country (audience) and brands that would support the "stars"
Asian: Your top Korean, top Japanese, Top Taiwanese, Top Singaporean
European: UK, Spain, France, Sweden, Germany, Russia, Denmark etc
Now tell me, which countries can really allow players to make money from sponsorships? and which can only rely on salary and tournament earnings....
