Why are the oakland raiders so popular?

It must be because of the uniforms because of al davis the raiders havent won since john madden left.Btw the gruden era was the raiders buying players succesfully for once they got blown out in the superbowl when davis felt threatened by gruden and fired him then he went to the bucs and gruden outcoached bill callehan(an al davis apologist who was only hired because he kissed the #ss of al davis).The raiders are a joke of a franchise.If it wasnt for the lions and the cardinals and the browns they would be the worst franchise by far in the nfl.They have done nothing but live of their past in the whole al davis era.
