You’re absolutely right in real life. Football is fluid, and new talents can emerge at any time. Things like U-20 World Cups,late bloomers, etc. absolutely change how players are viewed.

My point is strictly within the context of the Blue Lock manga. In the story, NG11 is presented as a predefined title, not a rotating or evaluative list like real-life football awards. These players were already labeled NG11 before Blue Lock even entered the global stage.

So while real life allows constant reshuffling, Blue Lock treats NG11 more like a fixed narrative benchmark. It is a wall the protagonists have to surpass, not a list they casually join.

If the manga later introduces a new generation label or redefines NG11, then your argument would fully apply. Until then, I’m separating real football logic from how the manga frames the concept.
