Think so? He looked smaller than that to me. Maybe 5'11. Maybe it has something to do with his skating style.
But anyway, I think McDavid is the more talented player with the puck. He has a lot of speed and creativity. That said, I'm not convinced that he'll be a better NHLer than Eichel. If this were the directly post-lockout period, there would be no question. But the game is trending in a mucky, grindy way, and I'm much more sold on Eichel's size (he could end up around 6'3) and growing power game. He just seems like the better player for the 2014 NHL game, and on top of that, I think he's got the puck skills to play in an open format too. So in that sense, I take Eichel to be the safer pick. With McDavid you end up gambling a little bit more, because I don't think he's going to be a wide, sturdy guy like Crosby. I see him more as a wiry guy like a Datsyuk, and that can be a rough ride in today's NHL.
(and before somebody notes that Datsyuk is listed at a similar weight to Crosby—total stat padding. Zetterberg is listed around there and is actually about 175 lbs soaking wet.)
