If today's players are truly sissies, as you claim, then it's only a matter of time before a shrewd GM builds a rough team that will destroy them and win championships, leading to an adjustment by other teams copycatting the champion. You'll see the drafting philosophies change, who gets more icetime, who makes the NHL or not among borderline players, etc. It's a cycle.
The Maestro himself did a little bit of that in 2021 with his tall, physical Top 4 on the blueline, which worked like a charm until they met a team that was just too good. But I'm sure GMs took note, but it'll take a while to see the changes from these notes. People are jealous of us having Xhekaj just now. Tough hockey will return, because the history of this sport has shown that toughness works, as long as it's complemented with skills.
