2018 NHL hockey playoffs

It's been a while then I didn't do a journal about hockey.  

The playoffs begin soon in the 2018 NHL Stanley Cup championship.  Does the Pittsburgh Penguins will win for a 3rd year row the Stanley cup? Last time a team did it was the New York Islanders of the early 1980s. Will the new NHL team, the Las Vegas Golden Knight will win the Stanley cup in his very first year? Will the Nashville Predators who won the Presidents' Trophy for the regular season will menage to go to the Stanley cup finals again? Would the remaining Canadian teams, the Toronto Maple Leafs and the Winnipeg Jets will go further deep in the playoffs even in the finals to end "the curse of Gary Bettman" (since his arrival as NHL commisioner in 1993, no Canadian team had won the Cup since and the last Canadian team who won it was the Montreal Canadiens) or "the curse of Marty McSorley"? Will the Washington Capitals who did lots of good regular seasons, but was eleminated in the 1st or 2nd round of the playoffs will go further deeper in the playoffs (last time they go to the finals was in 1998)?  Finally, there's still the possibility of a Cinderella team coming out from nowhere.
