To be absolutely sure of not offending anyone, every NFL team should have the same name, the same logo, and all wear the same color uniforms.
I suggest they all be called "Team" as in the Washington Team, the Seattle Team, the Buffalo Team... And all their uniforms will be solid black. Yes, that will make it more difficult for QBs to pick their receivers from defenders, but hey, that's why they get those millions of dollars.
Tongue in cheek I presume?
Only a bit, methinks.
