I'd stick to what has worked best in the past
ND's W-L-T record vs. Southern Cal since the iconic Green Jersey Game of 1977, based on color of jerseys worn at the start of the game*:
Navy blue: 8-2
"Madonna blue": 0-1
Green (various shades): 2-3
White: 6-9-1
* -- In 1985, ND opened the game in navy blue jerseys but switched to green jerseys at halftime, despite already leading 27-0. They could have worn pink in the second half and it would have made no difference. ND won 37-3. Exactly one month later, Gerry Faust was belatedly forced to resign.
I'd suit 'em up in Navy blue on October 17.
