Those are some pretty drastically shaken up lines.
Suggests perhaps a couple things to me.
1. Maybe Schenn’s injury is worse than missing a game or two. If it’s a minor injury or a guy is just taking a maintenance day, they’ll typically just keep lines the same and put a spare guy in the hole of the injured player. Completely jumbled lines perhaps suggest that Schenn could be out a while.
Conversely, it could just be them shaking things up simply because things haven’t been good enough so Yeo is trying new lines. It’s probably more this, but wanted to mention point 1 as that might also be a factor. Hard to say but hopefully Schenn’s injury isn’t too bad. But whether it’s injury or not, he hasn’t looked quite himself so far this season.
