If you play them together for longer than a minute than you can maximize their combined ice time. If they are separated the max is two minutes.
I think the answer is a new blueprint but still having Matty and Willy on the sidewalls. Maybe go:
Knies
Willy-X-Matty
OEL
JT or Marner take the X and they max out minutes, or JT and Marner take the sidewalls on PP2 and PP1 has to earn the extra minutes.
How would you set em up and split time?
