My brothers in Christ... what you're talking about is a fever dream. The idea of Sid playing with McKinnon and Malkin with Kucherov is cute and all, but it's never happening. You can bet your house on them retiring in Pittsburgh.
Letang, maybe there is a small chance he finishes his career somewhere else in 2027 when Sid and Geno hang up the skates but I'd also bet on him finishing in Pittsburgh. This isn't a Ray Bourque situation.
The change in management was long overdue, and hopefully we get a coaching change too. But just because those things changed doesn't mean we ship out our HOF franchise legend centers who have chosen to lock in with the same team their whole career.
New GM will come in, hopefully acquire a new goalie by trade and do a re-tool (that won't involve 87 and 71) and then Pens will run the gamut until the wheels quite literally fall off.
