First off, you keep ignoring the part where my team wouldn't have Drai but would have the best D man in hockey. I think that would make a bit of a difference.
I'm not arguing it wouldn't make a difference, but was D really our issue in the playoffs last year? Seemed to me that tertiary scoring was our biggest issue, and we still should have won the series if not for reffing/coaches challenge screw ups.
Second: Drai flourished to some extent against the Ducks because they had to put so much attention to covering McDavid. He also was obscenely lucky. Either way, i don't really put much weight in small sample sizes like a single seven game playoff series.
Of course he flourished because McDavid was their primary concern, but he also flourished playing against Getzlaf's line the majority of the time. Nylander did nothing this playoffs despite only seeing Bergeron's line 30% of his ice time. He would be eaten alive trying to matchup with Getzlaf. Call it luck all you want, Draisaitl eats the ducks alive every time he plays them.
That's grit to me.
Ok. If you don't think that skillset is important in the playoffs, and especially to get through in the West then I'd advise you to watch more playoff hockey.
I don't think he necessarily will (though I don't doubt he'll improve in that regard given his age). I just don't think you necessarily have to play that way to be successful. There's more than one way to skin a cat.
A star like Patrick Kane can skin a cat a different way, but thats on teams with incredible depth, and thats due to the fact that he's twice the player Nylander is. You're also asking a lot more from a centre in this scenario, and Nylander just hasn't shown at all that he has what it takes to be that guy come playoff time in the west.
Drai's no Malkin and we don't have a Kessel.
see above.
Kessel is a better 5v5 player than Drai right now because he's more capable of pushing the play on a consistent basis. Regardless, I'd say they're close, which still leaves us with having 2/3rds of the talent up front as the Pens.
Weird that the better 5v5 player has been outscored the last 2 seasons at 5 on 5. I acknowledged your 2nd point here already, which is that yes we need another very good forward. Time will tell if Nuge can do that alongside McDavid, or if one of Yamamoto or Puljujarvi can develop into that. Who knows, maybe we win a top 3 pick tomorrow and we find that guy in Svechnikov/Zadina.
