Can't say I've heard anything like that.
I think it's worth repeating that I don't believe the Rangers are shopping Buch, so much as listening. I think it's a key distinction to make.
I've received a lot of questions about why the Rangers would shop Buch, and I don't think that's quite accurate. They're not calling up teams and gauging said team's interest in Buch. But if another team calls them and inquires about his status, the Rangers haven't instinctively been shutting down the conversation. They'll listen, they'll engage, etc.
Vesey was being shopped. Pionk was being shopped. To a lesser extent Kreider was/and probably will be again.
Buch is a guy the Rangers would consider moving, if they felt the risk was worth it. He came close to going to Edmonton, but that was because the Rangers were willing to roll the dice on that scenarios. And like most instances, Edmonton can't seem to get out of its own way.
