Carleton brought this up in a gdt. From the article, it speculates Kapenen and picks, or Kadri... I'm fine with the former depending on the picks, but it's hard to gauge where the Flames think they are in the rebuilding process. My guess is they wouldn't be moving a guy like Hamilton unless they were getting a young impact player back that can play right now, and I don't think the leafs have one I'd be willing to offer, apart perhaps Brown, and that wouldn't do it on its own.
