Let's be honest, nobody has any clue what's going to happen in game 7.
The only thing that is known, is that a lot of people will way over-react and build huge narratives off of it. Here's a sample of narratives to come:
If Leafs wins:
"Tampa's window is closed!"
"Tampa can't win without bubble hockey/cap shenanigans!"
"Leafs have broken the curse, they are unstoppable now!"
If Tamps wins:
"Leafs are cursed!"
"Leafs are chokers!"
"Leafs should blow it up, Dubas and Keefe are gone!"
As much fun as it is to roast other teams, none of these narratives are true or will become true tomorrow. This series, like a lot of series, could literally come down to one bounce. That's it. The reality is both teams are great teams, both capable of winning the cup this year and likely will for years to come.
