Just about the entire core group from last year is back for the Flyers. The division is more difficult and making the playoffs should be a stiffer challenge. Only the top four get in.

Here’s a look at the roster the Flyers will open the season with when Pittsburgh visits on Wednesday (5:30 p.m., NBCSN).

Projected lines

Forwards

  • Oskar Lindblom-Sean Couturier-Travis Konecny

  • Claude Giroux-Kevin Hayes-Joel Farabee

  • James van Riemsdyk-Nolan Patrick-Jake Voracek

  • Michael Raffl-Scott Laughton-Nic Aube-Kubel

Notable: Morgan Frost is the extra forward. He had goals in his first two career games last season and then went 18 straight without scoring before being sent back down to the AHL.

Defensemen

  • Ivan Provorov-Justin Braun

  • Travis Sanheim-Phil Myers

  • Robert Hagg-Erik Gustafsson

Notable: Shayne Gostisbehere had been paired with Provorov until he was declared “unfit to play” over the weekend with an unknown ailment. He avoided being placed on the injured list. ... Mark Friedman also is on the roster. ... Coach Alain Vigneault left open the possibility of dressing seven defensemen on given nights.

Goaltenders

  • Carter Hart

  • Brian Elliott

Notable: Hart started 40 of the Flyers’ 69 regular-season games last year. Elliott made 27 starts and Alex Lyon started twice. In the playoffs, Hart started 14, Elliott two.

Comings & goings

Defenseman Matt Niskanen retired suddenly in October, and Tyler Pitlick, an effective fourth-line grinder, signed with the Coyotes. Veteran centers Derek Grant (Anaheim) and Nate Thompson (Winnipeg), acquired at last season’s trade deadline, also have moved on.

The Flyers signed Erik Gustafsson to a 1-year deal to take Niskanen’s spot among the blueliners, and the healthy returns of Nolan Patrick and Oskar Lindblom give the forward combinations better depth.

Money matters

Five largest cap hits: Claude Giroux, $8,275,000 (10.2% of salary cap); Jake Voracek, $8,250,000 (10.1%); Kevin Hayes, $7,142,857 (8.8%); James van Riemsdyk, $7,000,000 (8.6%); Ivan Provorov, $6,750,000 (8.3%).

Five best bargains: Carter Hart, $730,833 (0.9%), Joel Farabee, $925,000 (1.1%), Sean Couturier, $4,333,333 (5.3%), Phil Myers, $2,550,000 (3.1%), Brian Elliott, $1,500,000 (1.8%).

The taxi squad

NHL teams are required to carry a minimum of four reserves (and a maximum of six) who will travel and practice with the club, but not necessarily play. This group must include at least one goalie unless there are three goalies on the NHL roster. Players on this squad would not need to quarantine should any of the regulars test positive for COVID-19.

Forwards (4): Andy Andreoff (C/LW), Connor Bunnaman (C), Sam Morin (LW), Carsen Twarynski (LW).

Defenseman (1): Nate Prosser.

Goaltender (1): Alex Lyon.

Since we’re here, the use of a “taxi squad” dates back to the 1940s when Cleveland Browns coach Paul Brown would keep fringe reserves around by putting them on the payroll of owner Mickey McBride’s taxicab company. The players didn’t “actually drive cabs,” the Cleveland Plain Dealer once reported in a story about McBride’s legacy, “but they worked out with the team daily, ready to step up if someone got hurt.”
