or maybe people shouldn't be too emotional about something that is objective. there's a reason why the top 3 teams have always been tall for majority of the volleyball history. and yes, a sport that favors tall people, being short does make one physically inferior (for the most part).
now that teams are evolving and with the introduction of the libero position, the Japanese defense is no longer a far fetched skill in european teams.
Here you go again with 'objective' opinion which are very subjective 🤦 both Italian NT and Brazilian NT ruled for a long time with not necessarily tall players. Also Japan and Korea succeeded despite of their lack of height in general. Even USA didn't have the tallest players when they are at their peak. It is only Russia which always had tall players
