Miller was dominating both sides of the puck in his games, as well. He was a physical force, and more importantly, made few mistakes and looked incredibly mature given the recent switch from forward and the belief that he was a raw prospect. He looked like a polished prospect who could take over games, which is very rare for a true freshman. The fact that he likely would have led his his team in points from the back end at 18 is an enormous feat.
But, as I've said a few times , what separates him from Fox or Lundkvist or Rykov or anyone else, is that he profiles as an exceptional player--but he ALSO profiles as a ****ing behemoth out there, which the other guys don't. That's what gives him a clear edge. He can skate, he can defend, he can join the rush or create a rush on his own, and he can manhandle the opposition (and not just boys, but guys that are 23, 24 playing NCAA hockey). His physical profile just puts him on a totally different level, even if his other skills are similar to the other guys.
Zdeno Chara was a phenomenal player. He had so many skills, but he also could rag-doll the **** out of the opposition, which set him apart from many of his peers who also played a great two-way game. The same for guys like prime Lindros and Ovechkin--if they were 6'1", 205, they'd still be great. But instead they're ****ing wrecking balls on skates at 6'4" and 230+. Miller probably ends up 6'6" and 230, and impossible to move off the puck--and absolutely blowing away opposing forwards.
