Fact is, the Chargers were originally an LA team and the Raiders spent a few years there, as well.
Don’t forget the Rams.
According to wikipedia, the name “Chargers” was picked by the original owner because he liked the rallying cry “charge!” at Southern Cal games.
But the lightning bolt logo makes you think of an electric charge.
I saw a cover from a 1963 program of a Pats-Charger game in Boston, and it had a picture of a bunch of horses to represent the Chargers, as in “charger” being a knight’s horse.
I am still so far behind in football goings on. I still call the Rams LA, the Colts Baltimore. I am so “with it”! LOL
