A few years ago, I think it was the 2011 trade deadline, Tomas Kaberle garnered a 1st rounder, 2nd rounder, and then decent former first round prospect Joe Colbourne.
As a comparison, would you trade Markov to Pittsburgh for Simon Depres, a 1st rounder, and a 2nd rounder?
The idea is appealing to me but, I'm not sure I would trade Markov for a a package centered around a defensive prospect. We already have Beaulieu, Tinordi and to some extent Pateryn knocking at the door of the big club. There's only so much space for young guys on the blue line. Also, Despres is left-handed and we already have a clutter of left-handed defensemen. I would try to get a forward prospect with size to go along with a high pick. Markov does have a good value as a mentor for our young blue line though and has a lot of experience when dealing with the Montreal media which could also be useful for our young guys (although Subban and Gorges have them covered too on that aspect).
Isn't Markov what Pittsburgh needs?
Pittsburgh is at the top of the league in term of PP%. They don't really need a guy like Markov. They might be interested, but I doubt they would overpay to get him.
