If I were the NFL I would look at chartering some cruise ships and put two teams up in each ship. Dock the ships in the Seattle, Bay Area, LA, NY/NJ, Boston, Baltimore, Tampa/Jacksonville, NO, and Galveston/Houston.

I would basically consolidate the NFL back into their old 3 league formats of AFC/NFC West, Central, and East. Put all the West teams on the west coast to play in Seattle, LA and Bay Area. East teams would play on the east coast in Boston, NY/NJ and Baltimore. Central would play out of the gulf coast in NO, Tampa/Jacksonville and Galveston/Houston.

A lot of these cruise ships have the facilities a team needs and you don’t have to worry about players catching the virus from the staff since the staff lives on the ship.

This also eliminate air travel since the ships can move up and down the coast.
