Column: Bruins have already cost themselves more with David Pastrnak by delaying

When the Bruins open the 2017-18 season against the Nashville Predators on Oct. 5 at TD Garden, Boston forward David Pastrnak will be on the ice, alongside linemate David Krejci.

It’s that simple.

Pastrnak, who is a restricted free agent, is stuck in a contract stalemate with his employer, but it’s only a matter of time before an agreement is reached. It’s inconceivable to think the Bruins begin the season without their top-line winger, who produced 34 goals and 36 assists for 70 points in 75 regular-season games.

Pastrnak, 21, is actually in a position of strength when it comes to negotiations. If the Bruins are trying to get a so-called bargain, Pastrnak won’t let that happen.

“It should be an interesting situation,” said one league source. “If they don’t come to terms, and they have to trade him, they’re going to get crucified.”

Don Sweeney is on record, saying he’s not going to trade Pastrnak. Based on the team’s recent history of losing young talent that included forward Tyler Seguin and defenseman Dougie Hamilton, it would be a mistake of massive proportions if Pastrnak walked, especially for a team that needs an offensive threat.

Sure, he’s able to sign an offer sheet with another team, but that’s unlikely because it’s not a practice GMs risk for fear of future payback when they’re in a similar situation. Plus, the Bruins can match an offer sheet.

The Edmonton Oilers just signed 21-year-old forward Leon Draisaitl to a new eight-year, $68-million contract, with an annual average value of $8.5. That will likely be a benchmark for Pastrnak’s agent, JP Barry.

Depending on the terms, Pastrnak could be worth upwards of $7.5 to $8 million per season on an eight-year deal. It’s unlikely the Bruins will cut him a check for that much, so it could fall in the range of $6.75 to $7 million per season for six years. If it falls to a five-year deal, it would be $6.5 million per season.

Pastrnak’s deal should have been completed a long time ago, and now based on Draisaitl contract, it could cost Boston more.

Plus, there’s no reason why Pastrnak should be paid less than teammate Brad Marchand, who signed an eight-year deal worth $49 million prior to last season.

On the ice, you can bet Pastrnak will continue to get better.

“I don’t know why he wouldn’t,” said Bruce Cassidy. “He loves the game. He’s invested. You can see he’s growing into a man.”

Pastrnak also continues to develop his game at both ends of the ice, which will be crucial to the team’s success.

“He’s a good player,” said one NHL coach. “He’s a real good player.”

How much he’s worth to the Bruins will be interesting to learn in the near future.
