The Derby vs. Mill Valley was dubbed the game of the week if not game of the year by many because it pitted the two defending champs in their respective classes in the opening game of the 2020 season. 

But after an incredibly fast start by Mill Valley quarterback Cooper Marsh and the rest of the Mill Valley Jaguars, the Panthers trailed 35-7 at halftime in one of the most lopsided Derby Panther performances. 

Mill Valley won 45-14, snapping Derby’s 26-game winning streak that included the 2018 and 2019 Class 6A championships.
