It's early, but he didn't stand out that much in pre-season, and he didn't stand out that much in the last game. In terms of his long term development, it doesn't mean much, but in terms of him being ready for full time 2C duty next year, it does.
We can say this is a small sample size, and it is, but usually when a prospect is ready for a big role, they'll show it in pre-season and early in the regular season.
He can still take another step during the season this year, but the Avs should be thinking really hard about their options for 2C that don't include Newhook.
Newy could have a good second half of the season, but speaking of sample size, that's also a small sample size to give the 2C role to on a Cup contender. I feel like he's going to have to have a really good second half of the season, or playoffs, to make Sakic feel comfortable replacing Kadri with him.
If he doesn't take that step, I think there's a good chance Newhook could be trade bait for a 2C, because there aren't a lot of great options out there, especially that they can fit under the cap, and they're also pretty limited in terms of high end assets without a 1st next year.
