Big 5 RELOCATION (Co-Location) Some Team Cities I have on my radar. And realistically NOW.

Other than what I list, I'm sure that there are other professional sports franchises teetering on financial crap.

So let's think re-location (or co-location).
NO EXPANSION

Move 2 MLB teams, 3 or 4 NFL teams, 3 NBA, 2 NHL and 2 to 3 I'd personally like to see for MLS


What I would do right now, without expansion.

West Coast, Nord, Southern, Great Lakes, Los Angeles

MLB:

Oakland              for Portland
                           (or co-locate w/ Oregon for West Coast A's) ....throw Sactown in there,...or Inland Empire and Las Vegas as a co-locate
Tampa                 (co-locate for Charlotte and New Orleans) ....think the Coastal Run Rays
                                     (....and maybe even AtlantaX2, Louisville and Nashville) or Southern Run Rays
Rebranded:
= West Coast and Southern or Coastal Run.

NFL:

-Jacksonville         for a Southern team (west of/or around Tuscaloosa)
                 possibly even with New Orleans for co-location

           or  become the Canadian team, Nord Force across CFL markets

-Oakland         (West Coast Raiders, same idea as MLB)

-St. Louis   to Los Angeles

--New Orleans called "Southern"

Maybe no more "New Orleans", "Oakland", St. Louis or "Jacksonville"

Re-brand West Coast, Los Angeles, Southern and Nord

Los Angeles Rams
No more St. Louis.  Or move the Raiders back there to a new stadium and give Portland (and Oakland) the old St. Louis team.

---With consideration to keeping a team in St. Louis, instead of a team Canada, I'd co-locate with Louisville and rebrand "River City" or "Delta".

NBA:  

Ohio Barons, formerly Cleveland, ...plays throughout Ohio
River City (Pittsburgh, Louisville and St. Louis), formerly Milwaukee
Great Basin (SLC, Las Vegas) might come from the Timberwolves
Seattle Supersonics comes from the Utah Jazz and those silly Pelicans finally become what they should be called - The Jazz.

If something happened to Minnesota team, maybe consider a St. L, KC and Minneapolis as Heartland or Great Plains Wolfpack team.  Utah colocates with Las Vegas for the Great Basin Bandits or Pioneers

NHL:

Nashville is moved to Cleveland and Milwaukee with consideration for an upstate NY team near Syracuse.

Lake Front    or
Great Lakes

TorontoX2 and Quebec City will get their teams somehow.  I wouldn't mind Phoenix facilitating one of those or a Seattle team.
I wouldn't mind throwing in the Cincinnati area and Indianapolis for the Great Lakes team.  But that's a Cinci kid talking.
I wouldn't mind canning the Arizona Coyotes for the Western Coyotes for Phoenix and Seattle.

MLS:

Co-locate the C-Crew of Columbus, Cleveland and Cincinnati ????

I just know there are plenty of cities more deserving than my home town.  And MLS has yet to reach 30 teams.  ~20 now.

Go for San Antonio and/or Austin/El Paso and the likes of Boise and Las Vegas.
Atlanta and Charlotte are on the verge


In all:
Sorry Oakland, St. Louis, Cleveland, Milwaukee, Minnesota and Jacksonville
