Matthews started to play differently after hurting his shoulders imo. He hasnt been as tenacious on the puck ever since. We need him to stay healthy so to me its no big deal if he protects himself to an extent. Hyman helped a lot with the dirty work his rookie year aswell.
Marner's agent and people surrounding him contributed a lot to him squeezing every penny. Him being on the PK must've been a huge arguing point to why he wanted his salary on par with the other 2.
I've supported Babcock and think he's a good coach, but from what I've seen, he may have lost the room. The team comes out with no energy, the power play has no movement, players show no discipline taking poor penalties, the 4th line is overused, etc.
