Hi! I love to play fantasy football!
I have never played, but I know a lot of people love it.
Oh I see.. yeah, I enjoy acting as the general manager of the virtual football team!
I don't know too much about football, is this just like playing the real game?
Not really? It's like a computer game in a way. You pick the players that you think will perform the best in the actual games. Then get points based on how well they do, and if you score more than your opponent, you win that week.
That could be fun! Do you actually earn real money?
Yes! You could do it that way, and play for money each week. Or you could play money at the start of the season, and whoever has the best record, wins that money.
Wow, that does sound like fun. I know my brother-in-law does it, but I know literally nothing about football.
Its easy to start and they have ranking for each player, so you could just choose the players with the best ranks, then watch the game later or not. Its mostly a game of luck anyway. 
I may give it a try someday. Thanks for the info!
