The Cowboys seem obvious, but after that it gets interesting. The Seahawks seem obvious between Geographic proximity, their history in the regular season and playoffs, and their fans probably hating us equally to how we hate them. Past that, who else? I was thinking theres maybe 3 tiers:

Tier 1- Cowboys, Seahawks Tier 2- Packers, Raiders(?), Giants(?), Rams(!) Tier 3- Iono, maybe the Chiefs? The Vikings?

Let me know what you guys think.
