After reading the Flyers fan in the Flyers Win Streak thread on the main board who says the win streak proves that Couturier is overrated and expendable, I think the reason certain people bash Couturier so much is because he makes them feel dumb.
He's not a flashy player and he doesn't do things that show up in highlights so you actually need to know what you're looking at to see his value. I'm not even talking about looking at advanced statistics either, I'm only talking about the good ol' eye test. If you don't pay attention to the little things he does right then you might not be able to accurately understand his value, which is why we read people, even Flyers fans, who underrate him so much. It bothers them that so many on here think he's so good and they're not capable of seeing why. That's why idiots on facebook, twitter, other forums, and our dumbass beats don't get how good he is and think he's a bottom 6 checker.
