I'm looking at who is currently rumoured for trade, and it's mostly UFAs from the bottom 10 teams. Unless some bottom 10 teams start offering longer term players (like the Habs offering Pacioretty and Gallagher), if Byron is available I think the only guy who'd have more value overall around the league is Maroon. Byron has value, signed next year, PKer, can play any line, speed, goal scoring, he just lacks size. Guys like Vanek and Kane might be better players but at their cap hit and reputation, teams know if they are not in the top six they aren't going to be much use.
I think it's more likely to see a Weise type package. Weise got more than his value because he had a playoff reputation and some size, but a big part of why the Blackhawks wanted him was because he could play on any line. That's a big thing these days for teams looking to go deep in the playoffs.
