I was a fan in the 60's. The dark jerseys were totally considered bad luck. Some teams like the Commanders and Eagles would choose to wear white at home just to make us wear the unlucky jerseys. I'm thinking that most people that are fans today have no idea of the way things were.
Absolutely. The Cowboys had a pretty good first 20 years overall, but a losing record with those jerseys. I'm pretty sure the last game played in them was against the Eagles in the NFC Championship game. The Cowboys went 12-4 that season. I think 3 of those 4 losses including the championship game were in those blue jerseys. No other way to look at it, they had to go. Like you said, I wonder how many fans today know that's still the reason teams today force the Cowboys to wear blue. Even though it doesn't work anymore.
