lmao Prince. I'm not very competitive either, I would prefer to be a medium-good player on a medium-good team than a weaker player on a high-quality team. So much work...
Here I think the author is taking a moment to speak directly to the audience because of how fans can often say "Oh, you won't be any good until you play overseas in the big leagues" or "All players from our local leagues are weak compared to overseas". It's more complicated than that. Especially when we have an example right on the cover of the manga of a man who was very talented and went overseas and hurt himself almost immediately.
