that's the point of the mistake, they made the trade, they could have said let's trade Romanov and use the pick for the future, instead they tried to speed up the rebuild. They didn't have to do that, it's all about making the right choices and it was the right choice to trade Romanov for the 13th OA but what they did with that pick at least so far has shown it wasn't the right move. They paid scouts to inform them, someone should have pushed hard for players like Nazar imo, especially when they could have gotten the duo of Cooley/Nazar.
All GMs make mistakes, it happens, but you have to learn from them and you have to limit them or you end up like MB. Nazar was there for the taking, I think he's going to be a star in the NHL, but if Dach ends up working out then great. But people shouldn't have a problem pointing out a mistake as we all make them.
