The National Hockey League’s decision to allow a prospective ownership group in Seattle to submit a bid for an expansion franchise could have considerable repercussions.

It’s no secret the league has had interest in putting a franchise in the American Pacific Northwest for some time. Seattle has a long hockey history and is the current home of the WHL’s Thunderbirds. A competitive NHL franchise in that city would be a natural rival with the Vancouver Canucks.

Expansion to Seattle would balance out the league’s two conferences, with 16 teams in each. It’ll also be another nice cash grab for the exisiting team owners, as the proposed expansion fee of $650 million would go directly into their pockets. That’s because it isn’t counted as hockey-related revenue under the current collective bargaining agreement, an apparent lack of foresight by the NHL Players Association during the last round of CBA talks that they’re probably still kicking themselves over on a daily basis.

While the PA will miss out on in those sweet expansion fees, its membership will reap the benefits of the 23 new jobs created for the players and the additional hockey-related revenue another new franchise will generate, including higher salary-cap hikes and potentially lower escrow clawbacks from their salaries. Maybe, just maybe, that might pave the way toward smoother future CBA talks, avoiding another unnecessary work stoppage that only serves to test the patience of the league’s fans.

Expansion into Seattle, however, dims the possibility of the NHL returning to Quebec City. Despite the presence of a sparkling new 18,000-seat venue in the capital of la belle province, it’s still not enough to woo a new NHL team.

Location, of course, is the problem. The NHL doesn’t want to widen the existing imbalance between the conferences by placing another team in the East. Quebec City’s market size also pales in comparison to Seattle. Yes, it may be more hockey-mad and would be fueled as well by the rekindling of the rivalry with the Montreal Canadiens, but its media reach would be limited in scale. Factor in the lower value of the Canadian dollar in recent years, and Quebec City’s chances of landing an expansion franchise appears remote.

Or is it?

The city of Houston could be another potential location for an NHL expansion club. Tilman Fertitta, the owner of the National Basketball Association’s Houston Rockets, last month met with NHL commissioner Gary Bettman to discuss the potential of a pro hockey franchise in that Texas city.

Like Seattle, Houston has a long hockey history. It was home to the WHA Aeros of the 1970s and the IHL Aeros from 1994 to 2001. The city came close to landing an NHL team in 1997, when a group of local businessmen nearly succeeded in buying the Edmonton Oilers with the intent of relocating that franchise.

Should the Vegas Golden Knights build upon its current inaugural-season success and a franchise in Seattle follow suit, the NHL board of governors could be enticed to consider further expansion with new clubs in Houston and Quebec City. If potential owners in those cities are willing to pay the skyrocketing expansion fees and can prove those markets could sustain NHL clubs, it might not be a far-fetched idea.

Then again, maybe the league brain trust is keeping an eye on Houston and Quebec City as potential relocation cities for currently struggling franchises.

The impending sale of the Carolina Hurricanes to Dallas businessman Tom Dundon prompted some NHL followers to consider that club a relocation candidate. However, Bettman insists the Hurricanes aren’t moving. Besides, the earliest Dundon could move the team (if that’s what he wants) is 2024, when their arena lease expires. Trying to buy his way out of it would prove too costly.

Meanwhile, the future of the Arizona Coyotes has been in doubt for years. Bettman has stubbornly supported the franchise, currently in the midst of seeking a deal to build a new arena closer to downtown Phoenix. Should those efforts fall through, however, Houston could a tempting destination.

Should the New York Islanders’ bid to construct a new arena in Belmont Park fall through, their future in the New York area could be in question. With the Isles’ relationship with the owners of Barclays Center souring and Bettman insisting the club won’t be returning to Nassau Coliseum, Quebec City or Houston could become quick fallback plans, just as Winnipeg was in 2011 for the Atlanta Thrashers.

Houston could also be the future home of the Calgary Flames. Negotiations between the Flames ownership and the city of Calgary over a new arena are downright frosty right now, to the point where team co-owner Murray Edwards recently voiced his pessimism to his fellow league governors over the prospects of getting a deal done.

Edwards also said the Flames aren’t for sale. However, that doesn’t mean the current ownership won’t threaten to relocate if they can’t get the city of Calgary to bend to their demands over the distribution of the construction costs.

To the surprise of no one, the Flames want the city to pick up more of the tab than Mayor Naheed Nenshi is willing to spend. With Nenshi recently reelected to a four-year term, don’t be surprised if Murray and Bettman start ratcheting up the relocation threats.

Many NHL pundits doubt the Flames are going anywhere, suggesting it would be difficult for Edwards and Bettman to justify leaving a strong hockey market with a rich history. Don’t kid yourself. If the Calgary city council is unwilling to bend, the Flames will be in Houston before you can finish singing, “All My Ex’s Live in Texas.”

And they’ll justify it by painting Calgary’s municipal politicians as the bad guys for robbing the good folks of the Stampede City of their beloved hockey team, leaving the league no choice but to move to a friendlier city with a better arena.

Of course, this is merely all speculation. Seattle’s expansion bid could fall through. The league could decide that 32 franchises are quite enough. Maybe Quebec City will suffer the same fate as Hamilton, which built a big shiny arena over 30 years ago in the vain hope of attracting an NHL team. The Hurricanes could stay put in Raleigh, the Islanders could get their new home in Belmont Park, the Coyotes could get new digs in Phoenix and the Flames and the city of Calgary could eventually hammer out an arena deal.

Still, given the promise of the Vegas Golden Knights, the prospect of a successful franchise in the Pacific Northwest and the ongoing uncertainty facing several existing clubs in their current markets, the effects of a successful expansion bid in Seattle could be felt throughout the NHL over the next decade.
