I think you are highly over-rating the NCAA and the level of competition based on the fact you think Newhook has jumped over other prospects like Broberg, Soderstorm, Podkolzin whom are all playing VS professionals. You also seem very upbeat about NCAA'ers like Zegras, Boldy, Caufield.
Podkolzin for example plays in the 2nd hardest league in the world with the KHL and he is one of the youngest player in the KHL this season. He finished the year off with something like 8pts in last 12 games when the coach finally started trusting him and his young linemates.
Broberg and Soderstorm are both playing important roles on their SHL teams.
The NCAA is a developmental league, the KHL and SHL are far from it. Its a professional league.
Think about it for a second, anyone that has ever played on a local beer league knows the difference in levels of the top division in beer league hockey compared to the bottom division of beer league hockey. Now use that same perception and magnify it 10x and youll see the diffence between NCAA and other professional leagues.
The NCAA plays what, 2 games a week with very little travel?
As good of a year that Newhook is having in the NCAA i dont think he has surpassed the likes of Broberg, Soderstorm or Podkolzin at all.
Hockey writers did a January article ranking the best and toughest leagues in the world. Heres what the ranking looked like and many would agree.

3. Elitserien ( SEL- Sweden)
2. KHL

*Edit*
Podkolzin just popped in a goal in game 2 of KHL playoffs round 1. He has 1G 1A in 2 playoff games.
