Who holds it comes from the games on file: the winner of the latest regular-season meeting since 1968 (bowl rematches aren’t played for it); a tie leaves it with the holder (the usual rule; the article doesn’t say). The rivalry’s article counts the games for it: Wyoming leads, 32–⁠27. From Wikipedia’s list of rivalry games and the rivalry’s article (CC BY-SA). More on the Bronze Boot.
