Well, that's because frankly, it's bullshit. People rode Dowd and others out of town on the same note and he's a contributing 4th line member of a SCF team.
Even if Amadio plateaus, he's providing 10g 20p from the bottom lines and has some of the best metrics on the team and IS showing improvement in all areas but production. It goes back to the issue this forum has blaming depth players. It would suck if he's just Trevor Lewis because some of us expect more, but that doesn't make him 'not an NHLer.' I mean, people were saying this same thing about Alex Iafallo as recently as this preseason. It's insane.
He needs to sit and think but waiving him is the red button option for some reason since no one has taken his job yet anyway.
