My problem with Frost is if he's was an elite prospect, he'd be our 3C and pushing to be our 2C at 20, Barzal, et al.
The fact that he seems to be limited physically (i.e. hasn't developed strength and doesn't look to have the frame), and he doesn't show elite elusiveness (straight line speed is overrated, see Point) says he's one notch below that level, Neither his NHL or his AHL play screamed elite prospect.
So if Frost isn't going to be elite, but just probably very good, he's no longer above York, Zamula or Brink.
In which case D-men win all ties followed by centers and then wings.
