Wasn't appointing Coach Hong Myung-bo a wise choice for the KFA?

‌
Looking at it,
since the national team isn't coming together,
couldn't they have chosen Coach Hong
because he has the charisma
to unite them as one?
In the current football scene, who else besides Coach Hong
has such strong leadership?
From the KFA's perspective,
it seems like they made the best choice.
I can now somewhat understand
why they said
he sacrificed himself for Korean football.
