He wasn't riding the coattails of a borderline dynastic WHL team like Pouliot did. Pouliot wasn't even the highest scoring defenseman on that Portland team in his draft year.
And why would it even be a bad problem if Addison was Pouliot 2.0? If you can get a bottom pair OFD out of a late 2nd rounder, you're happy with that. Addison wasn't a #8 overall pick like Pouliot was, so it's really not a problem if he only ends up a bottom pair OFD like Pouliot currently is.
Addison has bigger "bust" potential IMO. Just the fact he's an offensive Dman lends itself to being more prone to flaming out.
Hallander was mighty impressive against men from all accounts and plays a style that is conducive to being at least a bottom 6 staple with the ceiling more or less becoming a scoring line glue guy.
Ranking prospects isn't just about ceiling. It's about balancing expectations with reality IMO. Which is one thing this entire forum has a hard time with.
I'll take Hallander because he's already shown he can hang with adults, is versatile and seemingly has an incredible work rate/ethic. Yeah, Addison might have a bit higher peak, but I also think his chances of not panning out are significantly higher.
To me, that makes Hallander the superior prospect.
