The only trade for Kuz I would think about would be for someone like ROR, if the Blues also needed a shakeup. Caps would probably have to add though, IMO.No absolutes. The rule of thumb is that if you trade the best player you get less back. I would rather motivate Kuznetsov than trade him. I cant imagine trading him and having a better team right away.
I could be suffering a lack of imagination.
