None.
Pro sports should contract (sp). Too many teams in the NBA and MLB.
NHL has 4-6 teams in serious peril.
NFL at 32 is fine, would prefer at 24 or 28.
I am so happy Jerry Jones is having trouble finding a sponsor for his new staduim. Financially teams do not prove a worthwhile return on investment for cities spending over $250M+ to build arenas/stadiums.
Like other businesses, have the owner fit the bill themselves.
No need for a pro team in LV, too many non-natives.
San Antonio would be a good choice for Baseball, but the Astros and Rangers would protest and football would be a tough sell as San Antonio has more Cowboys fans than Dallas.
