This is kind of a messy question altogether. And actually you've asked two. Has Scheifele proven he's better at hockey than Couturier? How about has Scheifele proven he's better at hockey than a fried egg? What constitutes proof? And what aspect of hockey? They don't exactly play the same game, the same position, the same quality of opposition.
The bolded part really annoys me because I'm an English teacher.
My giant complainy posts are full of grammatical mistakes and typos (and fake words like complainy), but what you said and what you mean are two hilariously different things. You asked whether or not I think that my opinion is that other people think Scheifele is better than Couturier.
I'm pretty sure that my opinion is that other people won't agree one way or the other. But then again, my opinion might
also, and as well be something else too. Anybody see what I did there?
