I think you're wrong here. Even if you forget about the fact that he was the only one of our forward "core" to actually produce (5 goals 3 assists in 7 games). Nylander did things that even he doesn't typically do. He threw some some nice hits and seemed to play on Turbo for most of the games.
Fair if you think we should sell high, but i'd say he isn't part of the problem. Always the last guy to leave the rink, always their for the optional skates, and while you're right he put up points against a team that wouldn't have normally made the playoffs, what does that say about Marner and Matthews who combined just barely beat out Nylander's total points for the series.
