Save traditionalist rants for later (tried to make everyone give up something) Raiders, Chiefs, Broncos, Chargers to NFC. Euro team goes to AFC. New North American cities are NFC: STL, San Antonio, San Diego? Portland? All central/west. Then Texans are only AFC team not in East coast I think. Swap them over to NFC for someone. Ends up like (new teams+, swapped conf*) AFC D1, London+, London+, Dublin+, Germany+ D2, New England, New York, New York*, Philly* D3, Pittsburgh, Baltimore, Indy, Miami D4, Buffalo, Detroit*, Cleveland, Cincy D5, Carolina*, Jax, Atlanta*, Tampa* NFC D1, Seattle, Arizona, Portland+, Vegas* D2, LA, LA*, San Fran, San Diego+ D3, San Antonio+, Denver*, Houston*, KC* D4, Chicago, Green Bay, Minny, St Louis+ D5, Dallas, Tennessee*, New Orleans, Washington (AFC D3 and NFC D5 I don't love, but I got all the AFC teams as East Coast/Euro). And just two East Coast teams in the NFC. Also split up the new NA teams in separate divisions for competetive reasons (Euro division is what it is) Edit. Maybe swap Washington and Miami, but I was trying to leave a token rivalry for Dallas too, which obviously leaves no good fit for a location based realignment. Edit2. Or let Dallas keep their rivalries intact but they get to be the one non Eastern Time Zone team that has to travel to Europe every year, and basically keep the NFC East intact but in the AFC (might need to rename the "A" there), then move a few things around elsewhere.
