Game notes: Chemistry on the ice can be a tricky thing; just ask the Panthers, who are trying to recapture the high-scoring formula they had in storming to the Presidents’ Trophy last season with the NHL’s best record. (Just, uh, don’t ask them about the playoffs, after they flamed out in a second-round sweep by the Lightning.) Of course, they swapped out some of the ingredients of that formula when they pulled off the offseason’s biggest deal: shipping forward Jonathan Huberdeau and defenseman MacKenzie Weegar — who combined for 159 points — to Calgary for 25-year-old star Matthew Tkachuk, who had 104 points himself.
