when the Cowboys away jerseys changed from royal blue to navy blue? I have a "bet" with a friend of mine about this. I say it was somewhere in the Staubach era, like '78-'79. he says it was in the early 80's. Now I do not mean when they started wearing the navy blue with silver/white numbers. I am talking about the navy blue with white numbers. The reason I am saying '78-'79, is because I have seen Mitchell & Ness Staubach throwback jersey in the navy/white away jersey and it said "1979" on the tag. If anybody knows the answer, please post it for me. Thanks.
