Pavel Buchnevich
Drury and Laviolette Must Go
I think some of the 5's are just being tossed out because they're fast, good skaters. Kreider's edge work isn't a 5 in my opinion, neither is Gilmour, or Skjei. They might be a 4 because they're great at one and good at the other, but not great at both.
It depends how we are judging it. And there are some players like Shattenkirk, Buchnevich, Hayes whose skating might move up if its about how the skating plays in-games as opposed to pure speed.
