Is NFL is indeed American football, a mix of soccer and rugby yes or no

No, NFL (National Football League) is not a mix of soccer and rugby. While American football shares some historical roots with rugby and has certain similarities, it is a distinct sport with its own rules, gameplay, and structure. Soccer (known as football outside the U.S.) and rugby are separate sports, and while they all fall under the broader category of "football" in various contexts, they have different origins and gameplay styles.
