I'd say Marner was more awful than Matthews, but does it really matter...
Marner just looked like he had amnesia and had no idea what was going on or how to even handle a puck. Matthews just looked like his feet weren't in the game, he wasn't going to dig in and pucks were rolling away from him.
The Domi era looks like it should come to a close. Max came in last year and played with a nice edge and looked like he could have some nice chemistry with Matthews, but this year it just looks like he just doesn't have it.
