From Ryan Kennedy's mock draft:
10. Edmonton – Zack Kassian, RW, Peterborough, OHL. Oilers want more grit and size; Kassian has both in spades.
Kassian's well back of the best players in this draft offensively; I don't doubt that he'll be an NHL'er, but I do wonder if he'll be able to crack the top-six on a consistent basis. Besides, he's almost certainly a year or more away from being an NHL player, and probably three to five years away from having a serious impact; there's very little sense in addressing today's needs 3+ years from now.
