Has there ever been any discussion of how a specific sports game PoD could have immediate and clear effect on the course of non-sports history, outside of intangibles (like a how game affected the national mood,* or general butterflies)? For example, how a high school or college game affected the academic careers of non-athletes?
*e.g. how the 1970 World Cup might have affected the 1970 UK Election

Perhaps if cooler heads prevailed and the match was moved, that could have allowed for tensions to ease.
