At least you could educate yourself on the circumstances before commentating.
If the situation was that they simply wanted to get rid of the old coach with not much plan on how to go from there... like, say, just hauling in some random guy from out of the blue, then yeah, it's bush league.
However, in this case, the replacement is someone who already was the incoming U20 head coach, he would have taken the reins of this team after these 3-4 remaining games anyway. And he was also the outgoing U18 coach, meaning he was familiar with pretty much all of the players in this squad. And he was already present in the city, watching the games, they didn't even have to airlift him in at a moment's notice.
When you bother to look those things up, it starts to make a lot more sense.
