Well, they started in Los Angeles, and have a built-in fan base already, better than bringing the Jaguars there, there’s no history there.
The Chargers played only their first season in 1960 in L.A., and then moved to San Diego, 51 years ago! There is no Chargers fan base in L.A. In fact Los Angeles fans hate San Diego teams. The black gangstas and Hispanic gangs of L.A. love the Raiders because of their pirate image. If the Chargers move to Los Angeles, they'll suck and draw fewer fans, just like the Clippers (who moved there when San Diego refused them a new arena).
