There is a new ECHL team coming into the league next season: Tahoe Lake Monsters in Nevada. While nothing is "official" yet, this will be the Vegas Golden Knights/Henderson Silver Knights affiliate.
Currently VGK had signed a one-year deal with the Savannah Ghost Pirates for the current season. There is nothing announced, or rumored that I can find, about who they will affiliate with.
There are currently 4 NHL teams and 1 AHL team that do not have affiliations:
No AHL or ECHL team:
Carolina Hurricanes
No ECHL affiliate:
St. Louis Blues (AHL: Springfield Thunderbirds)
Columbus Blue Jackets (AHL: Cleveland Monsters)
Arizona Coyotes (AHL: Tucson Roadrunners)
No NHL affiliate:
AHL: Chicago Wolves
ECHL: Savannah Ghost Pirates
While many of the affiliation agreements are one or two year term there is not enough published to detail them all here; only those that are known to be ending for certain.
These teams seem to have well developed and logistically intact affiliations:
Pittsburgh <-> Wilkes-Barre/Scranton <-> Wheeling (25+ years affiliation between 3!)
Detroit <-> Grand Rapids <-> Toledo
Montreal <-> Laval <-> Trois-Rivières
Boston <-> Providence <-> Maine
Colorado <-> Colorado (Loveland) <-> Utah
Philadelphia <-> Lehigh Valley <-> Reading
New Jersey <-> Utica <-> Adirondack NY
Minnesota <-> Iowa <-> Iowa
Chicago <-> Rockford <-> Indianapolis
Vegas <-> Henderson <-> Lake Tahoe
Toronto <-> Toronto <-> Newfoundland
NYI <-> Bridgeport <-> Worcester
Florida <-> Charlotte <-> Estero, FL
Washington <-> Hershey <-> South Carolina
These teams have a good relationship but some logistical issues:
Vancouver <-> Abbotsford <-> Kalamazoo, MI (off and on affiliation)
Edmonton <-> Bakersfield <-> Fort Wayne, IN
Ottawa <-> Belleville <-> Allen, TX
Calgary <-> Calgary <-> Rapid City, SD
Seattle <-> Coachella <-> Kansas City
NYR <-> Harford <-> Cincinnati
Winnipeg <-> Winnipeg <-> Norfolk
Nashville <-> Milwaukee <-> Atlanta
LA <-> Ontario, CA <-> Greenville
Buffalo <-> Rochester <-> Jacksonville
Anaheim <-> San Diego <-> Tulsa
San Jose <-> San Jose <-> Wichita
Tampa <-> Syracuse <-> Orlando
Dallas <-> Austin <-> Boise
Rumors
ECHL stated Expansion focus is to be at 32 teams grow in the west.
Arizona rumors are Reno, NV due to Merulo connection and a new arena being built there.
I'd like to see Jacksonville Icemen get "promoted" to the AHL and become the Lightning AHL affiliate and then Syracuse Crunch become AHL affiliate for the Carolina Hurricanes.
This would line up the AHL pretty well with logistics and each team having an AHL squad.
The ECHL would then need to expand by 4 teams to get to 32 and play musical chairs to improve logistics.
There aren't any credible AHL rumors that I've seen for Carolina. Anyone know anything or hear anything substantial on AHL/ECHL expansion/affiliation changes?
