Serious Sherlock? Tampa was in the AFC West their first season? Wow.Yes! I remember the AFC/NFC thing with those teams.
Tampa was in AFC West, Seattle in NFC West the first season. Then TB moved to NFC Central, Seattle to AFC West.
I'd have to do research to know why they were aligned in one conference then shifted to the other the following season -- maybe so established teams were more likely to play them (?)
TB didn't have a natural geographic fit until NFL reorganized to the 4-division N/S/E/W format.
I'm sure it was just a thing to be tolerated for the first year, to be fixed the next year with 'redistricting'. Interesting though.
