No he really wasn't. He put up points but he was largely not a factor most games. His skating was off (which Babs even said) and he wasn't taking over games like he has been known to do, he was just going through the motions.
The Matthews early this year that was dominant was pushing his way in between the puck and the player. He was using his size and elite stick to retrieve the pucks, and then his elite ability to protect it to draw players in for space. Then he is able to either set up the guys or get to the net to clean up that play he made.
Last years Matthews looked like a guy not willing to battle for the pucks. Not willing to outwork the other team for the puck, etc. And the main factor was he was still injured.
