Tbh I don't see them underestimating Ekblad/Barkov with this list at all, those are some damn good players that are ranked higher. Every d-man before Ekblad should be ahead of him and there's only like 2-3 guys (MacKinnon, Panarin & Kuznetsov IMO, then again I'd have ROR ahead of Barkov) that could/should bump Barkov up. All in all, they're right around where they should be and I wasn't even expecting Barkov to be on that list (due to lack of media coverage / media sexiness in general) when I started going through it.
And if you're suggesting that someone else from our roster should be on that list, take a look at the names on that list again.
