Sorry, I'm probably guilty of offering some not-so-serious name suggestions.
"Titans" seems generic, but it actually derives from Nashville's Parthenon, a replica of the original Parthenon in Greece. Titans are characters in Greek mythology.
I've stated before that I want a name that is directly, specifically related to the city of Washington, D.C., or the surrounding DMV. I really don't like when names are generic or unrelated to the city/region in which they are situated.
So, for me, "Lions" is not good because there are no lions in Detroit. It's just a generic name. Their baseball team, the Tigers, is just the same. It's unrelated to Detroit. "Pistons" is great because Detroit is The Motor City and pistons figure largely in the function of car motors.
Some form of "wolves" seems popular among many to replace "Commanders", but there are no wolves in the DMV. There used to be before they were eliminated by hunting, but they are no longer present.
So, I may be in the minority, but I want a name that is specifically D.C. and/or DMV.
So, I'm partial to names like "Presidents" or "Senators" or "Representatives" or "Founders".
