It does nothing for Armia and Lehkonen. Completely unrelated. Labanc clearly took a hit for his GM. And while everybody praise him for being a team player, he's incredibly stupid if you ask me. If he injures seriously this season he's never going to see that money.
Actually an arbitrator will look at comparables. And the habs will surely use a contract like this to a 50pts guy to put some downward pressure. So it will bring down the median.
