Looks like it's not just Leafs fans who won't shut up about Marner.
Media spread the allegations about Marner during his last year plus in Toronto. Treliving didn't correct them.
Media instigated it recently via questions to Tortorella, McCrimmon & Tulsky (who tried to trade for Marner)
Brind'Amour jumped in.
The media was doing their job, triggered by Marner leading the playoffs in scoring - which contradicts the spin he got run out Toronto on.
I think Hughes brought it up himself. According to Hughes, Montreal's top line isn't enough and without better depth can be shut down (like many teams with one good line - like Matthews-Marner's)
McCrimmon has explained it twice: Vegas has a deeper team than Toronto - that has allowed Marner to thrive in the playoffs.
The media was digging into the bogus narrative questioning "DNA", his ability to play in the playoffs, etc and how he's contradicting that by leading the playoffs in scoring now (like he led the Leafs over 9 playoff seasons).
That narrative now has to be widely perceived as in tatters because there seems to be consensus among all of them - the Leafs lacked depth.
The narrative might shift some again. Because Brind'Amour realizes Marner can hurt them as much as anyone so Marner's line or Marner may be the #1 target of the Hurricanes defense as Colorado tried. Eichel's line or Stone's line may benefit. We'll see.
Like Eichel said: Marner is “shutting a lot of people up right now” and that is not an unreasonable a story for the media because he's proving people wrong.
