RNH's hockey intelligence was incredibly highly touted in his draft year. Media everywhere were falling over themselves to gush about his puck I.Q.
Eventually, you do need some physical abilities to match those brains, though.
Both Nico and rnh have physical abilities, just because they don't have the amount of gifts Mackinnon does, doesn't mean they have none. Mack hasn't matched his rookie year yes in part because of his crap team, but also because he is just not that smart.
Rnh showed a ton of potential in his rookie season, and he was thrust into a mess, exposed to horrible coaches, and forced himself into a two way forward. He's still got all the offensive talent.
People are never going to accept that Nico is going to be a top forward because of all the bs said about this draft. The depth of it is weak, but everyone took it as being the entire draft is weak, and so every prospect must be. The top end was great, Nico is great, (I hate Patrick as a prospect but I totally get anyone who thinks he will be great). No McDavid or Matthews doesn't mean that the top players will wind up 45 point 2C. If people viewed Nico extensively in junior, he's fast, great hands, one of the best defensive forwards in the q, and incredibly intelligent.
