Well boys and girls I am proud to say that I was right about who would be in the Stanley Cup Finals. I got how many games it would take for each team to win their series (Vegas won in 6 games when I said it'd take 7 and Washington won in 7 games when I said it'd take 6), but I'm happy to say I was right in that the Stanley Cup Finals will feature the Vegas Golden Knights vs. the Washington Capitals. So who will win? Well that's not as simple as it may seem, but I'll do my best to answer that question. Let's compare each team and see if we can come up with an answer.
Goalies

Washington - Braden Holtby
Between these two goalies, it's a close one but I think the edge goes to Vegas. Marc-Andre Fleury has won three Stanley Cups, all with the Pittsburgh Penguins. This year he went 29-13-4 with a 2.24 GAA. In the playoffs Fleury is 12-36 with a 1.68 GAA, which explains why the Golden Knights are in the Finals. His best performance of the Western Conference Finals game in Game 4 of the Western Conference Finals when he made 35 saves in a 3-2 Vegas win over the Winnipeg Jets. Fleury has experience, knows what it takes to win in the playoffs and knows what it takes to be able to hoist the Cup. Washington's Braden Holtby is not slouch. Holtby went 34-16-4 with a 2.99 GAA. In the playoffs, Holtby is 12-6 with a 2.04 GAA. Holtby saved his best for the playoffs, which is why Washington is in the Finals. His best playoff performance game in Game 7 of the Eastern Conference against Tampa Bay when he stopped all 29 shots he faced in a 4-0 win that sent the Capitals to the Finals. Both teams have extremely talented goalies, but the edge goes to Vegas.
Star Players
Vegas - Jonathan Marchessault
Washington - Alex Ovechkin
Both of these players have been tremendous for their respective teams, but I believe the edge goes to the Capitals. Alex Ovechkin is probably the best player the NHL has seen since Wayne Gretzky. He led the NHL with 49 goals in the regular season and has 12 so far in the playoffs. Ovechkin has speed and shot that looks like a Nolan Ryan fastball. Vegas' Jonathan Marchessault is pretty good himself. He finished the regular season with 27 goals and 75 points, just 3 behind team leader William Karlsson. He leads the Golden Knights with 8 goals and 18 points in the playoffs. Both players have carried their teams through the playoffs into the Stanley Cup Finals, but the edge goes to Washington.
Defense

So my prediction is that we are in for one of the best Stanley Cup Finals in NHL history. An expansion team versus the best player in the NHL in 25 years. I believe that the Cinderella story of the Vegas Golden Knights will strike midnight and be over. The Washington Capitals will win the Stanley Cup and will do it in 7 games.
