The same way there’s hesitation in drafting Russian players, there needs to be more hesitation in drafting American college players.
I don't think all teams need to hesitate, but some definitely do, and for various reasons.
From what I've heard re: the Gauthier situation (Charlie O'Connor, Philly beat reporter, talked about it on his podcast, can try find the episode later if you want), BC's head coach made a really strong pitch to Gauthier to convince him to play in the NCAA for another year. Gauthier wanted a similar pitch from the Flyers, so when he told them he was considering playing another year in the NCAA and Briere said they want him to turn pro but would support him staying in the NCAA as well if that's what he wanted, Gauthier interpreted that as the Flyers not wanting him badly enough and wanted out.
Similarly, Friedman reported earlier this year that one of the reasons McGroarty decided to go back to college is because the Jets couldn't guarantee a full-time roster spot for him (kinda a no-brainer considering Perfetti still isn't always a lock, but that could change with Bones retired now), and he'd rather play at UMich than in the AHL.
So while some of this might have to do with "I don't want to play in Winnipeg" or "I don't want to play for Torts" and that kind of thing, I think these players want to feel valued and wanted by a) their teams begging them to turn pro and b) pretty much "guaranteed" NHL roster spots. If a team is comfortable with that then they should draft as many NTDP players as they want. If not, they should probably hold off.
