IMO, the situation is very different.
Terzić did/does have issues with individual players, not an actual rebellion of the whole team. Furthermore, unlike the Polish girls, Spasojević (and others) weren't forced to publicly outright speak against Terzić (even if the conflicts were public knowledge).
Also, Terzić at that point already had big successes with the NT in his CV, so the federation had reason to put their trust in him. Nawrocki doesn't.
I don't think the president of the Polish federation is right to make the comparison at all.
