I'm skeptical the Flyers go all-in on Hamilton. But they acquired Hayes proudly declaring he was a big, 2-way center.......and not a puck skilled, cherry picker. So, by that logic, I suppose Hamilton could be a 2-way stud? Jones makes more narrative sense.
I think Douglas is one of the best offensive defensemen in the league and an absolute top pair quality play driver. I'd be happy to have him, but I'm slightly ambivalent at the same time. I do think he's more a top pair weapon than an actual "#1," which is fine. I like weapons! It is hard to ignore how monstrously good Slavin and Pesce are as defensive defenders with skill. There's symbiosis there.
But I don't think the Flyers and Vigneault would know how to use him to his strengths. It's not hard to see them actually playing to his flaws. Historically, AV doesn't understand offensive defensemen. Hamilton is maybe the best goal scoring defender in the league and would go to a team that already has a #1 who bombs away endlessly. He'd go to a dysfunctional PP that overemphasizes point shots as is. Possession isn't prized here. If you can't fit an among league best talent on your team, that's your problem, not the player's. And that's my point. For half the price tag, they could let Sanheim follow the Hamilton playbook, but they don't even know how.
