I think they should do this for the top two pairings:
Gryz/McAvoy
Lindholm/Carlo
Gryz/McAvoy already have superb numbers together, and Lindholm could help calm Carlo down and give him room to work, build his confidence, etc. This could result in some of the best top 4 shutdown pairings in the league, and if they really needed a extra shutdown line then they could bring Hampus back up with Charlie for certain games/situations like they did with Chara/Seids
