It's not offensive lol it's just incorrect. They're not fairly young.
The average age of Kreider, Zibanejad, Panarin, Fox, and Shesterkin, right now today, is 29.2.
Dougie Hamilton is 30 and he's old enough to be everyone else's father on his team. Hischier is 24, Bratt is 24, and Hughes is what, 21?
Chabot is 26, Tkachuk is 23, Norris is 23, Stutzle is 21, and Sanderson is 20.
That's what a young core looks like.
If Laf and Kakko develop enough to be considered "important players," then it looks a tad bit better. Right now they're spare parts.
