I disagree. These teams are largely driven by guys under 30. Eichel is 28, Marner is 28, Dorofyev 24, Barbashev 29, Hanifin 28, Rasmussen 28, Howden 27, Kolesar is 28... For Carolina, Stankoven is 22, Aho is 28, Ehlers 29, Svechnickov 25, Jarvis 23, Blake 22, K'Andre Miller 25, Nikishin 23...
Florida was no different. Barkov, Bennett, Tkachuk, Verhaeghe, Reinhart, Lundell, Ekblad, Rodrigues, Forsling, Luostarinen, Jones, Montour all under 30...
I think it's fine to have a handful of older players, but it's very rare to see a team win when their primary drivers are 31+, or the majority of the team is 31+.
