Irony
You think he works hard, I'm not sure how you can watch him play, watch other players play in the playoffs and then come to the conclusion he works hard.
Good for you if you played pro, I really mean that, it's an impressive feat.
But we obviously have 2 completely different standards of what hard work looks like. For example when I watched the playoffs, guys like Benett, Barkov, Reinhart Tanev, McDavid, Hyman, Ekholm, Marchand, Nylander, Mackinnon were guys who stood out because they were competing hard. I didn't see even 50% of that effort from Marner.
I will never agree with anyone who claims Marner works hard though.
