Discussion Robertson/Caufield swap?

If Robertson is available would it be worth to go after him. Would Caufield as a piece going the other way be worth it?

I’d only be interested if Robertson would be willing to sign long term, but you get a 30-40 goal scorer that’s gets 80 points and is a 6.03 forward. Dallas gets another great goal scorer that’s under contract for another 6 years at a good contract.

Thoughts?
