Diamondplate on white has not been seen since the Dennis Dixon era of 2006-2008 personified by Oregon's last visit to Michigan!
Chrome-White-White is a relatively common combo of late. At Texas Tech last year (and with eggshell at UW, but we wont mention that game). This appears to be the 10th time since 2017. They wore it three times in 2018. But if you count gray/carbon fiber it's an even more common look going back to Chip Kelly's years.
