I would do this

You lose that Philly trade

This trade makes no sense. All of those guys have potential NHL futures and certainly worth more than draft picks especially with their contract value.

No way Matthews signs that deal either. If it's 13 million it's 3 or 4 years max.

Then he can go kick rocks in AZ.

Making decisions about the best player in franchise history because of hurt feelings would be unbelievably stupid.

If he is unwilling to sign a long term deal to make him the highest paid player in the history of the cap era, he clearly doesn't want to be a leaf or care about the teams success, this would obviously be a decision made this year. if he indicates he won't sign long term. You have to trade him if thats the case.
