So then this Shanahan--Dubas--Keefe trifecta is permanent thing until success happens.
However if you pay 3 players X $11 mil as among the top in the game, you're essentially buying a playoff spot annually because all you have to do is finish in the top 8 teams in the East and qualify for the playoffs, since no playoff success doesn't force change no matter how many years that takes to achieve.
Big market team spending to the cap ceiling, against rebuilding teams like Buffalo, Ottawa and Detroit who spend near the cap floor and $10-15 mil below the Cap ceiling shouldn't be too hard to beat out to get into the top 8, particularly when the previous GM gifted you a 60 goal scorer and generational franchise #1C, after pulling the team out from the bottom of the league and handing over a +100 point playoff team to start.
Would it qualify as "blowing up the program" by changing the coach and running it back with the same core group players year after year?
If the answer is "YES" the the previous question and making the playoffs alone = 100% job security for GM and Coach then one can conclude to force change and a major shakeup, its going to take the Leafs to either 1) Miss the playoffs or 2). Have Matthews depart in 2 years when his contract ends chasing success elsewhere, forcing the Leafs into a rebuild as this current window of Cup competitiveness closes.
So then we know going forward that as soon into the next regular season the Leafs team qualifies for the playoffs, the bar for management job security threshold has been breached, anything thereafter irrelevant as they will "run it back" the following year continuing to tinker around the edges only, to make sure you don't fail to qualify for the playoffs by making a change in personnel that causes it.
