Why? What is there to suggest that Nylander is some potential great? Even if you think a lot of his skill, he had some black marks against him regarding size and character. The idea that there's this massive gulf between the skilled Euro and the big, dumb Canadian alternative (Nick Ritchie) that the Leafs would usually pick is just not realistic.
I'm one of the naysayers who didn't like the pick, and who believe that Nylander will be a pretty big-time bust. But even still, even if I accepted the idea that Nylander would hit his ceiling and turn into a solid top-three forward, it's ludicrous to think that he's ever going to be so good that this pick will be looked back on as some kind of franchise-defining moment.
Too many people here are making way, way too much out of signing Nylander. It's pathetic, really, the straws that Leafs fans grasp at. Even this summer, it's sad how so many here are buying that the Leafs have made big changes to the team simply by shuffling the deck with a couple of d-men and the bottom six. This team will never win anything because of serious deficiencies in the character and skill-set of its core players, namely the likes of Phaneuf, Kessel, Kadri, and Lupul. Roman Polak and LOL Leo are not going to suddenly vault the Leafs into contender status.
