Made a few changes to your list of unserved major league sports markets:
NHL.
Hamilton
Winnipeg
Quebec City
Portland
Seattle
Remove:
Milwaukee
(Milwaukee could be considered as a good hockey market, but I seriously doubt that it can support more major league teams.)
NFL.
Los Angeles
Add:
Portland
Salt Lake City
NBA.
Kansas City \ St. Louis
Add:
Seattle
Louisville
San Diego
Remove:
Las Vegas
Anaheim
Vancouver - The NBA. can work in vancouver if the team was marketed right
(Las Vegas in truth really isn't a place for any major league sport. The LA area already has two NBA teams. And there's no great reason to think that the NBA should try going back to Vancouver before a fairly long list of other cities.)
MLB.
Portland
North Carolina (Raleigh)
Add:
Albuquerque
Vancouver
Remove:
Montreal - Same as Vancouver with NBA. if the team is marketed right & if the build a new ballpark MLB. can work in Montreal
Tennessee
(Same with the NBA in Vancouver, I don't see any particular reason for why MLB should go running back to Montreal. Also not sure that Tennessee can really support more major league teams.)
CFL.
Halifax / Moncton
Remove all the below:
Quebec City
Western Ontario - London \ Windsor
Victoria
Portland Or.
Spokane Wa.
Up State New York - Rochester \ Syracuse
Bosie Id.
Milwuakee Wi.
Alaska
(Why should the CFL try to be in any of those places?)
MLS.
Completely different list:
Miami and / or Orlando
Atlanta
Charlotte
El Paso
San Diego
Of course, in some of those cases, it would be a matter of whichever major league got there first, because a city such as Portland probably couldn't support two more major league franchises.
