The NHL is a decade into the salary cap era, but with a ceiling of $73 million, there still exists the possibility of big spending for franchises willing to open up their wallets.

Here are three teams that should spend big in free agency when the signing period opens July 1.

Detroit Red Wings

The premature departure of Pavel Datsyuk and the subsequent trading of his contract to the Arizona Coyotes has opened up a window of opportunity for the Detroit Red Wings.

With a 25-year playoff streak barely held intact this past season and a new arena set to open its doors for the 2017-18 season, general manager Ken Holland needs to ensure roster stability by filling Datsyuk's top-line center spot with high-end talent.

Steven Stamkos, of course, would fit that bill, and with almost $20 million in available cap space heading into free agency (and possibly more to come if Johan Franzen goes back to the long-term injured reserve), Holland should be able to put together an appealing contract.

Dylan Larkin could end up being the center to follow Steve Yzerman and Datsyuk in leading the Red Wings to a Stanley Cup, but the Red Wings should spend big to sign Stamkos and ensure a happy ending at Joe Louis Arena and a fresh start at Little Caesars Arena.

Buffalo Sabres

The market for Stamkos will be hot, and Buffalo Sabres general manager Tim Murray has openly stated he's ready to chase the big fish in free agency.

While a superstar like Stamkos would certainly be a welcome addition, the Sabres are already quite deep down the middle, with Ryan O'Reilly, Jack Eichel, Tyler Ennis, and Zemgus Girgensons heading up the depth chart at center.

No longer in tear-down mode, this is a team well on the rise from the very depths of the league's basement, and the Sabres might be better served spending big on other needs, particularly on the blue line and on the wings.

Billionaire owner Terry Pegula is not averse to spending, and is committed to building a winner in Buffalo. A splash or two in free agency could put the Sabres within striking distance of a playoff spot as early as this season.

The Sabres also have nearly $20 million to work with, albeit with budding star and restricted free agent Rasmus Ristolainen still to re-sign, as well as Girgensons.

New York Islanders

The New York Islanders will be under new ownership in 2016-17, as Jonathan Ledecky and Scott Malkin assume majority control while longtime figurehead Charles Wang retains a minority stake.

Upon being introduced as new owners back in 2014, Ledecky and Malkin made it clear their intention was to bring a fifth Stanley Cup ring to Long Island.

Well, it's time to back that up.

The Islanders are coming off a second-round playoff loss at the hands of the Tampa Bay Lightning, as well as a debut season in Brooklyn that brought mixed reviews for Barclays Center as a viable home for NHL hockey.

General manager Garth Snow is looking to re-sign valuable two-way center Frans Nielsen to a new deal, but the club decided to let Kyle Okposo become an unrestricted free agent, leaving a big hole on the top line.

The Islanders have the luxury of having John Tavares locked in to a ridiculously team-friendly deal for the next two seasons, and while they'll want to ensure they can meet his asking price on what will likely be a big ask on his next deal, there exists an opportunity to sign a big-name free agent or two in the meantime.

Snow has more than $15 million to work with and has to sign restricted free agent Ryan Strome to a new deal, but ownership should try to make a splash in order to chase that fifth ring and entice fans to make the trek to Barclays deep into next spring.

Matt Cullen will let you know when he's done.

The veteran and two-time Stanley Cup champion reportedly wants to return for a 20th season, according to Sportsnet's Elliotte Friedman.

Cullen will be 40 in early November and Friedman adds that the Pittsburgh Penguins would love to retain his services but the salary cap may make that problematic.

Drafted way back in 1996, Cullen had 16 goals and 16 assists, and dressed in each of the Penguins' 82 regular-season games. He had four goals and two assists on the Penguins' march to the Cup.

Cullen made $800,000 in salary and against the cap last season.

Wade Redden is back in the NHL.

The former All-Star defenseman has been hired by the Nashville Predators as their new assistant director of player development, the team announced Monday.

The 39-year-old retired in 2014 after playing in over 1,000 NHL games. Redden last suited up for the Boston Bruins, but spent the majority of his career with the Ottawa; and one of his former teammates is particularly excited to see him making the move to Tennessee.

Colorado Avalanche general manager Joe Sakic stated his team's intent to buy out the final year of defenseman Brad Stuart's contract Monday, according to Mike Chambers of the Denver Post.

Stuart's $3.6-million cap hit would remain on the books, but a buyout would save the team $1.2 million in cash. The 36-year-old was limited to just six games last season due to a back injury.

After trading Nick Holden at the draft, Sakic is hopeful the remaining ice time on the blue line can be filled by younger players like Nikita Zadorov, Chris Bigras, and Duncan Siemens instead of trying to find a replacement via free agency.

"What we're doing is allowing more ice time for these guys," Sakic said of his blue line. "We're going to get our young guys on the ice more because these are the guys that, in a few years, are going to be our (main) guys."

Erik Johnson, Francois Beauchemin, and Eric Gelinas remain under contract for the Avalanche, while Sakic says he has already made an offer to restricted free agent Tyson Barrie.

Andrew Shaw got the long-term deal he was hoping for.

The Montreal Canadiens have signed the 24-year-old forward to a six-year contract extension, the team announced Monday.

The contract is worth a reported $3.9 million per season through the 2021-22 campaign for a total of $23.4 million, according to Sportsnet's Chris Johnston. The deal does not include any no-trade or no-movement protection.

“We are very pleased to have agreed to a long-term deal with Andrew Shaw," said general manager Marc Bergevin. "As I mentioned last Friday following his acquisition, we are adding a solid character player to our team, a reliable player who plays with grit and a two-time Stanley Cup champion with the Chicago Blackhawks over the past five seasons.

"Andrew will add more leadership to our team. I had the opportunity to discuss with him over the past few days, and I sense his determination and excitement in joining the Canadiens' organization for many years to come."

Shaw was acquired by the Canadiens during the first round of the NHL draft Friday in a trade that sent a pair of second-round picks to the Blackhawks, whose salary cap situation made them unable to negotiate a long-term deal with the young winger.

A fifth-round pick in 2011, Shaw helped the Blackhawks win championships in 2013 and 2015. Last season, he posted a career-high 20 assists in 78 games.

He will add more grit to a Canadiens lineup that already features Brendan Gallagher, who is locked up through 2021 himself.

The Colorado Avalanche retained the rights of former No. 1 overall pick Nathan MacKinnon by giving him a qualifying offer Monday, and general manager Joe Sakic assured that the Calder Trophy winner "isn't going anywhere."

Though a new deal is expected, the potential contract length of a new deal is "up in the air," Sakic told Mike Chambers of the Denver Post, adding that he has already met with MacKinnon's representatives.

If the two parties opt for a shorter "bridge" contract, the Cole Harbour, Nova Scotia native would become a restricted free agent once again at the end of his next contract.

MacKinnon bounced back following a difficult sophomore campaign with 21 goals and 31 assists in 72 games this past season. He recorded 63 points in his rookie season.

Other restricted free agents to receive qualifying offers from the Avalanche on Monday included defenseman Tyson Barrie, goaltender Calvin Pickard, and forward Mikhail Grigorenko.
