#10 Oakland A's

Adopted by: Almighty Ambrose Nation (Chicago), Orchestra Albany (Chicago), Spanish Cobras (Chicago)
Why: The Ambrose and the Albany share the same first letter as the Athletics, while the Spanish Cobras rock the green A's caps to represent their primary color.
Complex says: Three gangs from the same city rockin' the same hats? Shit must've gotten real dicey in those shootouts.
