Hoffman and Karlsson were fast skaters but never did we hear this much about how fast a particular player was. Formenton will be lights out if his hands can keep up with his feet and he adds a bit of size.
As for Batherson the guy can score goals. Watching his highlight reel from last year, he probably could have had another 6-7 goals on breakaways alone. Dorion and Boucher, from what I heard on the radio, think he's the most talented out of all the prospects.
Tkachuk will never be a Crosby. Those expecting him to be will be disappointed. He will put up more points than his brother so 60+ points a season is pretty good for someone of his skillset.
