Yeah, I mean, Geno's showing his age. That's all. He's not good enough to prolong the rebuild or anything--shit, not even Sid is on his own.
Geno's said in the past he wants to play his final season with his real number 11. So if he switches numbers this summer or mid-season next year, that'll probably be a significant indicator. Dunno if he follows through on that plan though.
As for the "get younger" thing, that doesn't matter. That was always a talking point for the argument that this team should try and pull a Washington to extend their window. Ship's sailed. Team's dead. The age and composition of the roster doesn't matter. If Geno wants to stick around, keep him until he's done. Trade whatever has value (EK, Rust, Rakell).
Also, I don't believe for a f***ing SECOND that Geno knows who Tommy Novak is, let alone his first name.
