The NHL's conference finals have arrived, and if you asked around in September, the four teams remaining were some of the most likely answers to the question, "Who will win the Stanley Cup?"

We didn't get here the way many would have imagined, though. In the East, there can be no debate that the Florida Panthers and New York Rangers are the best teams, and were the best teams over the course of the season.

The West, however, was a little more surprising. The Dallas Stars battled the Colorado Avalanche and Winnipeg Jets all season for the No. 1 spot in the West, with all three teams having spells at the top. The Edmonton Oilers had times during the season when they were wholly unconvincing as playoff threats, including a dismal start that saw them nine points out of a playoff spot in November, leading to the dismissal of coach Jay Woodcroft.

In our series previews, we look at specific areas: key points of difference in the series, the X factor, which team my model favors and the reasons why, along with a projection on the series result.

The model is a neural network that accounts for player strength, offensive, defensive and special teams performance, goaltending, matchup ratings and rest. As the model ingests data, it improves, with the heaviest weights on recent play. The model allows for players to be added and removed, with their impact on the game results measured.
