The past and or historical cost doesn't matter. What matters is the price teams will pay in a bidding war and you have contenders like Vegas, Colorado, Toronto and Washington who all appear DESPERATE.
Colorado just re-signed their backup and traded a significant amount for Kuemper.
They will give that tandem at least 1 run in the playoffs.
They may be desperate for a more experienced #3, but not enough to trade a 1st.
