There is no chance he'll be a Top 10 pick and you should look at the comparable players.
If you’re picking between him and a player from the OHL/CHL/WHL/QMJHL,USHL or the European or Russian Super Leagues vs BCHL there is no comparison and loses any tiebreaker. He’s might seem to be a good prospect, but is he actually better than fellow BCHL alum Tyson Jost - two years ago? Jost statistically seems to be a better player with more points in fewer games. High IQ and strong defensively.
I like Newhook, but not Top 10. He is near the top of possibly the 3rd tier of Forward prospects.
1st - Hughes, Kakko.
2nd - Turcotte, Dach, Cozens, Zegras, Podkolzin, Krebs, Boldy and Caufield
3rd - Newhook, Kaliyev, Lavoie, Suzuki, Tomasino.
DMen - Byram & Soderstom
There are 10 Forwards considered better players and possibly 2 DMen (Broberg/York are possibilities) that would push him into the mid-teens.
However, you want to use different metrics BCHL is simply not a strong league. They need a longer transitional period to adjust into higher levels.
Most recently you can compare players from the league and their NHL success. Jost was better statistically and defensively was drafted at 10th OA and continues to struggle. Disappointing for such a high pick, but still young and the AVs remain patient with his progress. Kyle Turris is likely the best player from the BCHL with substantially higher BCHL numbers and most comparable. Turris averages nearly 50 point seasons, but given his struggles with NSH might be more suited to 3C or borderline 2C. He was drafted 3rd OA, a poor return for a player selected so high.
There are certainly 12 players ahead of him. BCHL is a weak league and it's his decision to choose the easier path, but the lower competition cannot be ignored. Comparable players from the league Turris/Jost are not exactly outperformed players drafted after them. Thus, supporting their high BCHL numbers were significantly inflated and they haven't translated to NHL success.
I'm guessing he will be selected by MIN or believe 12-18 range.
