The puck drops Wednesday night in three series, and so the NHL’s death march to the Stanley Cup begins.

The defending Stanley Cup champion Pittsburgh Penguins get right into the hatred with a match-up against their arch-rivals from across the state of Pennsylvania. The Philadelphia Flyers overcame an early-season 10-game losing streak and climbed back into the playoffs under the watchful eye of head coach Dave Hakstol.

They also had a little bit of help from Claude Giroux, who had one of the best bounce-back seasons in recent memory as he went from scoring 58 points in 2016-17 to a career-best 102 points this year.

Giroux had never scored more than 93 points in any season and had been on a downward trend since 2013-14 when he scored 86 points. He scored 73, 67 and 58 points over the next three seasons.

Giroux started percolating again this season, and got plenty of help from Jakub Voracek with 85 points and Sean Couturier with 76 points.

The Flyers can put the puck in the net, and they should have an opportunity to do that quite a bit against the Penguins. Pittsburgh gave up 250 goals this year, and the defense appears to have slipped quite a bit from the last two years.

Could they pick it up in that area in the playoffs? It seems unlikely, even if goalie Matt Murray gets back to top form. The Penguins defense leaves the net-minder in a vulnerable position too much of the time. Still, they will come at Flyers with Sidney Crosby, Evgeni Malkin and Phil Kessel, and they can light it up as well as any team when they get off to a hot start.

This should be the highest scoring series of the first round, and we see the Flyers handling the favored Penguins without going into a panic. The Flyers win this thrilling series in six games.

Rematch: Bruins vs Maple Leafs

These two teams got together in 2013 and played a spectacular seven-game series. Well, at least the finish was overwhelming, and it was thrilling from a Boston point of view while it was brutal from Toronto’s perspective.

The Bruins built a 3-1 lead in that series, but the Maple Leafs were undaunted and rallied to tie the series at three games each. The seventh game in Boston appeared to favor Patrice Bergeron, David Krejci and Zdeno Chara, but the Maple Leafs led 2-1 after two periods and stretched the advantage to 4-1 near the midpoint of the third period.

That’s when the Bruins mounted a comeback for the ages, getting a goal from Nathan Horton to come within two. Late goals from Milan Lucic and Bergeron tied the score before the end of regulation and turned TD Garden into a cacophony of noise.

It didn’t take long for Bergeron to score the winner in overtime, and ruin the hopes of long-suffering Toronto fans. The Leafs have not won a playoff series since 2004 when they defeated the Ottawa Senators in seven games, and they haven’t won a Stanley Cup since, gulp, 1967.

The Leafs and Bruins are a near-toss up in this series, with Boston having a slight edge because of the home-ice advantage. The Bruins are still firing away with Bergeron, Chara, Krejci, Brad Marchand and Tuukka Rask, but they have a slew of young talent making key contributions. David Pastrnak, Charlie McAvoy, Jake DeBrusk and Danton Heinen are among the youngsters that the Leafs will have to contend with.

Toronto is loaded on the offensive end with Auston Matthews, Mitchell Marner, William Nylander, Nazem Kadri and James van Riemsdyk.

The two x-factors in the series could be Rick Nash for the Bruins and Patrick Marleau for the Leafs. Nash was acquired at the trade deadline and made a quick contribution before being sidelined for the last three weeks of the regular season. Marleau scored 27 goals for the Maple Leafs, including five on the power play and five game winners.

We are expecting another seven-game series, and perhaps more heartbreak for the Leafs and their fans, as Bergeron either scores or sets up the series-decider in over time.
