Matthews hasn't been very good, but Marner obviously hasn't picked up the slack 5 on 5 on the top line without him.
It would be forgivable if Marner and Matthews dominate, but for how expensive that line is, it's been a disappointment 5 on 5 for the last 2-3 years.
Knies is one of our true bright spots on the team this year outside of old guys. He's stapled to Marner and Matthews yet the results haven't been great.
If your 1st line is a 1st line winger, two franchise players, you expect utter domination.
Marner with Domi and Knies should be able to put up goals and points 5v5
