You're misunderstanding what I'm saying.
Past outcomes do not affect future outcomes.
The Leafs no longer have to come back from a 3-0 defecit, they now have to come back from a 3-1 deficit.
You are including the stats of all the teams that got swept, even though the Leafs have already won a game.
Prior to the the Leafs winning, they had to come back from 3-0.
It's like if the Leafs win 3 in a row, are you going to argue they have to win 4 in a row even though 3 are completed or do they only need to win 1?
It is not a 3-0 series anymore, I don't understand why you think it is. It is now a 3-1 series.
Including all the teams that got swept as a way to lower the stats is disingenuous as it's guaranteed the Leafs will not be swept.
Either way, forget the odds. The games are played on the ice. Based on odds, the Leafs would have won this series anyway.
