If i had to venture a guess, it'd be about the Canucks general inclination to swing for the fences with their 1st pick on particular standout abilities.
Virtanen: elite skater, shooter, hitter.
Boeser: elite shooter, scorer.
Juolevi: elite outlet passer, puck mover.
Pettersson: elite dangler, hockey sense.
Hughes: elite puck mover and PP quarterback.
They've pretty consistently spent their top picks on guys who have identifiable elite traits at the expense of other weaknesses. I'm not sure Broberg really fits that. He's more of a well rounded guy with some weaknesses, who is also tall and a good skater. It doesn't really fit the trend.
It's the same thing that makes me wonder if they're really serious on Krebs.
Fair enough, although you could probably argue Broberg is an elite skate with elite size at the expense of a weakness with hockey IQ.
