He's not a 2C now, heck, not even a 3C. He might get there, sure. But how much time do the Avs have to figure that out? If Kadri doesn't come back, he will likely get a shot at some point. We'll see how it goes.
And again: If he gets good, he also gets really expensive pretty quick.
And NO, nobody hates Newhook. But with a team like the Avs, trying to win now while juggling with a flat-ish cap, all options are on the table. And Newhook is one of the few prime assets left to fill holes elsewhere. And long term, he is wasted in the bottom six.
