I swear I saw the Cowboys wear an alternate in the playoffs and the Lions might have too, as they ended up wearing their one game throwback for the rest of a season because they did so well in them. Not sure if they got some kind of waiver or what. They had solid silver helmets, solid royal blue shirts with silver numbers. Cowboys unis were white with a star on the sleeve and a different helmet. Looked like pre Roger-Staubach days unis.
R.I.P. Dad. I miss you. You will never be forgotten
