The "Shanaplan" is about to head into its 8th year. A project that was designed to create a sustainable, consistent contender every year, has failed.
I see a lot of people excusing the Leafs defeat because it was against a "really good" Tampa team, yet this deep into the project, the Leafs should also be a "really good" team.
You could argue changes could be at all levels - on the ice, behind the bench, in the press box, and at the board level.
It should all be on the table. Absolutely 0 reason to be married to anyone not named Auston Matthews at this stage
I voted 'Replace the GM and let them bring in a new coach', but I don't have a strong feeling yet of where I think this should go. I can see the reasons for keeping everyone. I can see the reasons for firing Shanahan.
But to expand on the first part of your post - Masai Ujiri took over the Raptors around the same time Shanahan took over the Leafs. He never had top five picks to draft a Matthews or Marner, and yet he put together a team that made the playoffs for 7 consecutive seasons (now 8 of 9), made
at least the second round for 5 consecutive seasons, won 9 total playoff series, and a championship.
A season ago the Raptors cratered in a Covid season, drafted in the top 5 for the first time in Ujiri's tenure, and promptly made the playoffs again. This season the Leafs won one more playoff game than a Raptors team that was supposed to be rebuilding/retooling.
Now to expect the Leafs to have done all that, maybe that's reasonable, maybe not. They are different sports. But as a fan of both teams, I can't watch the Leafs do what they've done and compare that to the Raptors and say that I am OK with where things are with the Leafs. Both organizations have tremendous resources. The results for the Leafs should be better. That doesn't mean management should be fired, but it does mean they shouldn't be untouchable, right up to Shanahan.
One final thing - Matthews is absolutely the only untouchable player on the Maple Leafs' roster. He's the best player in the world at scoring goals now and is irreplaceable.
