Just listened to this St Louis radio show where they talked about the rumor. They talk about Tkachuk multiple times, first with O Brien then again just before the 1 hr mark. Pretty thoughtful takes on it, including acknowledging that it's not very realistic, and that Calgary doesn't have to trade him, and that he's worth a ton of young assets. At one point one of the hosts says he's heard that the ask would be at least two first rounders and a top prospect, if they wanted to move him.
