Could this happen?

At the end of the NEL only 23 players will stay, all the others will not make the final selection for the upcoming world cup.

My question is: will something happen to the ones that don't make it?

I ask this question because imo it's dumb to waste all these unique designs and characters, I've seen many fans in this sub talk about how they love these side characters and that it's a waste that we see so little of them.

We may see some more of them in episode Nagi like we have seen with Hiiragi and Himizu but I watched a video on this (link will be at the bottom of this post) and if you watch Nagi and Reo's games up until the NEL arc not every side character will be shown.

Not only characters we don't know a lot about but also very popular characters will be missed, after seeing that the new BL cover player is Nanase, a lot of people speculate Zantetsu not making the squad. Not only him but others like Igaguri (not for me but app some of you like him), Nishioka, Neru, Niou, Darai, Hayate maybe even Kiyora will not make it and it would be a shame to see them all go. (imo)

I don't think it's bad to say goodbye to characters and introduce new ones but in this case it would just be such a waste.
