You take the money that would go to Strome and put it towards Hertl and then you make moves to make it happen.
They will probably need to find 8 mil to keep him. That's going to be difficult with the cap situation the Rangers have. I would think you could move Nemeth or Lindgren or maybe both and Chytil but you still have to replace that depth lost. I think the blue liners could be easily replaced but there's a lot up front to replace if they try to keep Hertl past this season.
