This is quite a good point.
In passing, I can't help but comment on how amazing it is to find yourself in the position of trying to convince other Flyer fans of this!! What a world.
I'm a fan from the Bullies era, that was my identify both as a fan and as a player. Still is. But the game has changed, drastically really. The need for skill to win in the NHL is not really debatable. See Makar, Cale.
The problem, as Torts has 100% correctly identified, is that we have a skill deficit, possibly a large one. Also not debatable. So, until we no longer have that deficit, guys like ZM and ND are likely going to play more than *those* young guys, because those young guys aren't skilled enough.
