I'm not intending to embarrass you with my responses, but you keep digging your heels in on a nonsensical position.
Other way around, perceived value on draft day is precisely what determines draft position, influenced by the needs of the team but most are adhering to a "BPA" strategy first and foremost. Teams create a draft board with extensive scouting and research, then take the top guy remaining when it comes to be their pick.
Nylander hasn't played long enough to have a fair NHL body of work to evaluate him on, but his body of work since draft day in other leagues is historical-level good, and his body of work in the NHL so far - with and without Auston Matthews - has been exemplary.
Nylander is top 10 and often top 5 on every reputable prospect ranking and he's regularly bumped in to the top 5 on mock redrafts - these things would not happen if his absolute ceiling was a fringe 1st line winger.
Stop relying on your super-human ability to analyze hockey with your eye test better than anyone else on a hockey-specific forum, look at the evidence and apply context, and give a little credit to the rest of the posters that probably know a little about the game as well (especially when they unanimously speak out against your position on this argument). Be willing to be moved off your position in light of new information, that's how we improve the strength of our arguments. And if you're just here to take up contrarian positions without being able to support them - isn't that just a waste of your time too?
