I didn't read the article.
The way it's supposed to happen is a team contends for a while then slowly drops like the Sundin Leafs. GM's are supposed to let it naturally drop, bounce off the bottom and depending on how well they rebuild they then climb to the next peak but they are often afraid of losing their jobs etc so they mess it up.
The current Leafs management also didn't let this happen naturally. They decided to dump top players and tank. The problem is that they hit the bottom with too many holes created by the tank and MUST stay at the bottom for longer to fill the holes. If they do, then the future is very bright but if they think that they are better than they are and do things like signing good goaltenders instead of letting the team naturally suck then they will bounce too early and never truly contend for a decade or more until they fall and bounce again.
We are at a crucial stage in the rebuild. Too early to start competing but a few great assets that trick you into thinking they are ready. It appears that Shanahan doesn't understand. We'll see.
