Young, skilled goalies don't come on the market too often. When they do, teams line up to try to acquire them. The selling team can rightfully expect a ransom.
Is that player worth two first-round picks? Well, in a trade market where Ivan Provorov fetches a first and a second, anything is possible.
With other goalies, such as Thatcher Demko, Jeremy Swayman, and Juuse Saros potentially being on the move, Hart's trade will have a major impact.
