When people get jealous, they speak nonsense.
The only reason why Volleyball World has pushed more about Ran Takahashi or Yuji Nishida because they have more views. If you look at FIVB website or their news, you clearly will notice that they shift their focus on digital platform heavily recent years. The average viewership of Japan highlight is over 300K when other teams are hardly reach 10K averagely.
Don't complain about it. All you can do is to share videos that derserve more promotion to your frinds/colleagues/relatives/communities to drive more views. Share on your social medias. When the viewership goes up, Volleyball World will push it.
You want Wilfredo Leon to be more discussed? Did anyone start a new thread about his surgery or about his performance? No. You just don't care to discuss it youself. You think a simple post can draw huge attention? A little stone can't make huge waves. Stop complaining, change start from you.
