This is incorrect. The Rams never wore these uniforms. The only white pants they've worn since the uniform change have been when the jerseys had gold on the side. These pants have a gold 'spear' on the side also, not blue piping, and were only worn with the white jerseys as someone mentioned before. I'll try to find a better picture of the pants, I know there's one with Warner and Az Hakim floating around somewhere.
They played 1 game in these uniforms and man am i glad they put them away!
