I'm talking specifically about the U20 in 2013 because I did not watch the U17 or U18 tournaments. I don't talk about what I don't watch. It's why I didn't mention it in my original post.
I watched every game of that U20 2013 tournament. Miller was not the team's best overall player.
That's my opinion. In that tournament, I'd put Galchenyuk, Trouba, Gibson (are we counting goalies?), Gaudreau, and even Jake McCabe before Miller. To not take into account Gaudreau's SEVEN goals because he didn't PK or is only a "skill player" is asinine.
Here's a link to the "Best Player of the Game as Decided By the Team"

Count how many times Miller's name shows up. Spoiler alert: It's 0.
Of Gaudreau's 7 goals, 5 came in the elimination rounds. To his resume, Miller did assist on 3 of those. If you want to talk about stepping up when it matters.
These are just my opinions. It's time to get used to the fact that two people can watch the same thing and see it differently. I should look in the mirror when I say that, but at least to my account (or to make myself feel better, I guess) I can try and post facts to back it up. Not just say "Oh my god, did you even watch the games".
