If you’re rooting for upsets in this year’s Stanley Cup playoffs, you’re more likely to find them in the Western Conference.

That’s what oddsmakers seem to think, at least, after making all four first-round favourites in the East roughly 2:1 favourites to advance to Round 2.

The biggest favourites in Round 1 are the New York Rangers and Boston Bruins. Both are listed as -225 to -230 favourites at Pinnacle Sports and SportsInteraction.

The Pittsburgh Penguins and New Jersey Devils are both listed in the -200 range for their opening-round series.

In the West, the only heavy favourite is the Vancouver Canucks, who are -200 chalk against the L.A. Kings. The St. Louis Blues are favoured in the -155 to -160 range at Pinnacle Sports and SportsInteraction, while the Nashville Predators and Chicago Blackhawks are -125 favourites in their respective series.

Chicago and New Jersey are the only teams in the first round to be favoured despite not having home-ice advantage.
