Yeah theyre a great team but they play a different style, theyre defensively focused and they dont have superstars like Mackinnon and Makar. I feel like even when everythings clicking over there, Rantanen probably wont be putting up 100 point seasons.
Another interesting thing is usage, Rantanen and Necas have swapped ice time basically.
Necas with Carolina: 18:05 per game.
Necas with Colorado: 22:43 per game
Rantanen with Colorado: 22:30
Rantanen with Carolina: 19:41
Carolina just spreads it out more.
