WHen I say consensus I mean a sure fire #1 prospect like: J.Hughes, Matthews, McDavid, (Yakupov and MacKinnon somewhat), Tavares, Stamkos, Crosby, Ovie, Kovalchuk, Lecavalier, Thornton, Daigle, Lindros.... Most hyped, if you will.
Hischier and Patrick were nowhere near that kind of "hype". It was an off year.
But yeah, why not end out being like MacKinnon? It could take 3-4 years until hes elite for all we know, and Hughes could possibly (but unlikely) end out just having a great rookie season a la: Ghostisbhere, Werenski, Ekbald, Myers.
Bottom line, its early for both. Hughes had an exceptional rookie season, no doubt, and I think he'll probably have a great career. But having a great rookie season, is still just one season.
Being the "sure fire #1 prospect" is Top 5 player in the NHL potential... see the list of players in my first paragraph.
