Hyman-Matthews-Kapanen
Johnsson-Tavares-Nylander
Marleau-Kadri-Marner
The premise is that Matthews, Tavares and Marner are split up, so Auston and John's wingers are interchangeable.
Reasoning: Each line has at least one player other teams will want to focus on and guarantees one of Matthews, Tavares or Marner will be facing a 3rd defense pairing regularly. As well, Marner should help get Kadri/Marleau going and ideally, provide 3 productive lines which are critical for the playoffs.
I think the Matthews/Marner pairing will mean opposing teams do what they do now with Tavares/Marner: Focus on covering the trigger man (Tavares and now Matthews). Of course, the result of that has been Marner shooting and scoring more. But I don't see a net gain from this move unless M&M somehow find a different approach that gets Auston going.
