Are all soccer players uneducated?

Looking at the guys doing the interviews, they don't act like adults.
Even though people are talking about landmine victims, these guys who are about to enlist are acting like complete idiots without reading the room...
Is it an intelligence issue?
The captain is just smirking about not going to the military,
and Yang Min-hyeok says his seniors were talking about the military and scaring him.
They said they played harder for military exemption than for medals..
How is it that not a single proper interview comes out?
