The Penguins are listening but they're in no rush, if they in fact trade him at all. And I think the reason they're in no rush is that some teams who don't accomplish what they're looking to do in free agency or on the trade market in the next 10 days may need to circle back to the Penguins. The market for Rust is already strong, but it may become even more robust as the summer goes.
Back to my comment about potential August trades above to start this article: There's still a world in which Rust is moved this week if a team really, really steps up, but I think it's more likely the Penguins wait it out.
