Betting nuggets for the second round

12:42 PM ET

Favorites had the slight edge in the first round of the Stanley Cup playoffs. Six of the eight series favorites won, and favorites overall were +0.85 units. It continued a profitable NHL season for favorites, which were +35.9 units during the regular season.

The second round of the playoffs has been full of upsets in recent seasons. In the past five postseasons, favorites and underdogs have split the 20 series equally 10-10. In individual games, favorites have been +21.6 units in this round in that span.

Overs have also been successful so far, going 31-18-2. The New York Rangers–Pittsburgh Penguins series went over the total in every game, becoming the first seven-game series in NHL history to feature at least seven goals in every game.

We have also seen puck lines become more profitable, as 75% of games were decided by at least two goals, compared to 49% in the past two postseasons.
