Learned from the first offer sheet with KK and Aho

This would be the path, and it would have to be Laf agreeing to it.

Very unlikely, but if it were to happen - this is the only way.

If he has a good enough year to make this worthwhile it'll cost more than the 3.5-4 you're saying.

KH won't do this but God do I wish he would.

The offersheet has to go over 7m to be unmatchable.
The rangers would match at 6.3 by moving goodrow and then jones in separate deals.
You're also giving up an unprotected first round pick, from a team that was just in the lotto, and hasn't added any major piece that should play immediately... I dont think Laf takes the canadians from a contender for 1st overall, to a playoff team.
