I would save Football and let American football die. American football, although popular primarily in the United States, is a more localized sport with less global significance. Therefore, I prioritize the broader reach and cultural impact of Football over American football.
I will save Formula 1 and kill NASCAR. NASCAR, while popular in the United States, is seen as less prestigious compared to Formula 1. Therefore, I choose to save the superior and internationally respected Formula 1 over NASCAR.
Traitor!
