I would've expected some Raiders gear at some point too considering they just won the title in 84. Maybe they took winning for granted and didn't realize that bum ass franchise wouldn't win again for the next 35 years.
Were LA brehs wearing Raiders gear prominently like that back then? I had to look it up, but that Gang City documentary with Turtle aired 6/5/1984, months after the Raiders won the SB. I didn't see not one dude in that documentary wearing any black and silver. And those were Santana Blocc dudes, they wear black nowadays I thought.
