Lol this is so going to fail
Dallas - Cowboys City. XFL won't catch on
Houston - Might be OK there.
LA - Saturated sports market. 10 pro teams plus USC and UCLA already based there. Rams and Chargers are struggling with their fans support
NY - Another saturated sport market. 11 pro teams already based there
St. Louis - Great choice
Seattle - Seahawks City. XFL won't catch on
Tampa Bay - Meh
Washington DC - Decent selection
Why not choose cities that are starved for professional sports teams? San Antonio, Columbus, San Diego, Portland, Orlando. Replace Dallas, LA, NYC, Seattle and Tampa Bay with these 4 and here is what you have:
Houston
San Antonio
St. Louis
Portland
Orlando
Washington DC
Columbus
San Diego
