Why are you cheering a team on to lose? This team is 4th in the NHL, betting against any team winning is the easy bet. If you don't like the team, why are you even here?
This kind of question and reasoning is as tired as it is not well contemplated.
Indulge me for one second, but that question is very similar to the boss who stands up and says... You don't like it...there's the door. This kind of thinking/statement is an insulator vs. feedback/criticism. It is crying for help to be left unchallenged, because in the challenging you may have to confront actual real issues that need addressing that you either can't or won't (or both) address. It is lazy, wrong, and ridiculous and is not something that comes out of a real leader's mouth.
In a similar fashion this kind of question is along the exact same lines of thinking.
All of us know that NOTHING is guaranteed when it comes to sporting competition. You always know an upset is a possibility. If you didn't, sports would lose most, if not all of its charm.
I know that I don't know what is going to happen...for sure. That is why I watch. That has nothing to do with the concept of understanding what has happened with this team in the past is most likely to happen this time, also, especially given the disparity in goaltending. And, the pedigree of back-to-back champions vs. a team known for losing in the playoffs. There is not much to be hanging your hat on here, and that isn't even mentioning the Leafs best goal scorer is mired in a 5-game slump, the longest of his season, and might be hurt more than we know.
If you want to fool yourself into thinking this is a flip of the coin, you're welcome to that, but I don't share in that and have expressed why.
