I know some people are leary about this part but I think coach stark has a point here. Eventually hinata’s going to have to work with other players and setters if he wants to make it outside the realm of high school volleyball. By then hinata will hopefully be able to stand on his own two feet more but somehow, given how furudate has presented the players and their strengths thus far, I don’t think hinata’s ever going to be the kind of player you look to for stability. Players like daichi, kuroo, yaku, asahi, taketora, tsukishima, iwaizumi, shirabu, etc are the types of players that center on stability. They’re the “foundations”. Players like hinata, noya, tanaka, lev, tendou, etc all center more on their wild natures. They attack, playing up their shock factors and using it to their advantage. That’s especially true for hinata who the series has emphasized is someone who draws his opponent’s attention even without meaning to. Hinata plays better if he can go a little nuts. His ability to draw attention to himself is one of his selling points as a player. It’s not bad or good, it’s just his thing.
So given all that, it’s not bad to know that there will be other people out there ready to play on hinata’s strengths when the time comes. Like the coach says here, he’ll have to keep improving until then, but he’ll probably still be at his best on a team that allows him to play a bit on the wild side. He’ll need people outside of karasuno who can handle playing alongside him and he’ll need other setters who can bring out his best qualities. Hinata can’t play with the same people forever, sad as it is, and no matter how good he gets, he’s not gonna get to play if his style clashes with literally every other player. Coach stark is pointing out that that doesn’t look to be the case, others who could play with hinata do exist out there.
Also keep in mind that this guy is the coach for the international team. He’s probably thinking of the future teams he could make here and this commentary is a mark for hinata, not against him.
