You must be a masochist. Do you really want a 7 to 10 year plan? The Panarin's and Eichel's aren't going to be racing to Calgary to help. It'll take forever. Most draft picks are 3 years minimum, so 3 good heavy drafting years is still a 6-9 year trickle. With no guarantees. Not sure that I love your plan, maybe sleep on it.lol
For me, it's just important to exercise exit strategies on Backlund, Tanev, Coleman, Hanifin and likely others. We can't be a retirement home nor lose players for little or nothing or overpay them. That already got us here.
There are definitely zero irreplaceable players on our roster, a large contingency of fans it seems need to watch other team's players and see equivalents.
We're simply not very good, without naming names. We all want them to be. But it isn't the reality.
Then also, you can't just throw your hands in the air and say get rid of everything. It's not all bad, I doubt it's as bad as it seems.
