he Rams are one of 9 teams this season that are NOT wearing the “color rush” uniform on Thursday night. The reason they’re not is because they present difficulty for TV viewers to distinguish (i.e., Jets cannot wear at Bills, Browns cannot wear at Ravens, Rams cannot wear at Seahawks for this reason).
When there is a conflict between Color Rush uniforms like those above, the visiting team (the Rams) is the one that must adjust.
Teams not wearing their Color Rush uniform for the reasons above have the option of wearing an existing uniform (which the Cardinals did with their normal road white on white) or a different/special all-white Nike uniform.
