answer:What is fantasy football? An online game where participants pick existing players and score points based on the performance of their players. Trades and free agencies are common. Is it just a betting pool? Sometimes people will place bets on whose team will do the best, but it is not “just a betting pool.” Do you pick players and create your own team? Yes. However, it is set up like the real NFL. Every team is in a league. League size can vary considerably. Each player exists only once per league; therefore, two participants cannot have the same player on their teams. Is there such a thing as a fantasy soccer league or fantasy baseball league? Is football the only sport that lends itself well to such an endeavor? Yes, just about every major sport one or more fantasy games.
