My point is playing Panarin with Ryan Strome, Ryan Spooner, Filip Chytil, Kevin Hayes, or any other moderately competent player (just naming some players they've had in recent years) was a better idea than playing him with Zibanejad and I've said this literally since the day they signed him. Coming into the year there was zero reason to think Strome would work with Panarin. He was coming off multiple bad offensive years (including his time with the Rangers the year before where he scored 1.3 pts/60). He was a third line quality player and it worked. There was no reason to think Panarin would work with Strome any better than he would work with Chytil or someone else (not Howden as he's too bad). It was just the first thing they put together and it "worked" because Panarin is one of the best players in the league and can work with most skilled players.
Stacking your two best players for regular shifts is just bad strategy. It means you have 60-70% of the ice time where your lineup is vastly weaker instead of guaranteeing you have one of the two on ice for like 60-70% of the tine. It works for teams like Boston who have other really strong players like Krejci/DeBrusk on the next line (Depending what you consider "work" as I'm pretty sure Pastrnak has better numbers with Krejci than Bergeron anyway) but it does not work for a team whose 2nd line would have been something like Kakko/Strome/Kreider and then a third line of Lemieux/Howden/Fast. The reason they split up Mika/Panarin isn't because they had Strome waiting in the wings it's because the team was too top heavy and needed more balance (and then Mika got hurt the next game so they stuck with it). Whether or not Strome was on the team that issue would have existed and they would have made the same change with someone else there.
