It's working well for Toronto!
Dubas isn't fit to carry Yzerman's jockstrap.
Remember SY navigated the cap for the last 7+ yrs with TB & only now they're in potential danger of losing a younger core piece, but even that is not a foregone conclusion.
Heck, Stan Bowman did a good job overall til ~2-3 yrs ago (trading Hjalmarsson was bad).
Pens GM's did the same.
What's your masterful solution?
BTW factoring in TVM, $10m Barkov, $9.5 Werenski, $9 Larkin will be ~30% of cap & are likely to look like bargain contracts by year ~3-7 (assuming good health/productivity). F'ing Taylor Hall would've gotten $9 from some idiot GM & he's a W, with 1 MVP season....there are other examples, feel free to look.
