Have you ever played fantasy football.  It is a game in which participants serve as the managers of a virtual professional team.
Wow, I have never heard of that
Its great.  The competitors choose their players and team rosters. 
OK..that must be an interesting game. I love football
Me too.  You can spend hours though playing it.  The points are based on the performances of the actual players in real life competitions.
Wow, that is cool
Yes it actually dates back to 1962! A guy called Wilfred Winkenbach designed a rulebook and system of organisation which would eventually be the basis of modern fantasy football.
Now I know the history,  you are really into football
