Quoting: papishark
High profile to me = top 50 league wide prospect. You arent getting him for Chytil after this year
Mark Stone was traded as a potential Rental and signed his extension shortly there after and the return was Brannstrom (maybe a top 50 prospect at the time) and a 2nd.
Going back to the Flames, Zary and a 2nd is very reasonable. We would need to include salary going back (hence Backlund). If that is negative value to the sharks, I would consider moving the 2nd to a 1st, but that is a big return on a potential rental, whether he signs an extension or not is not part of the deal.
