What impact does fantasy football have on football?

Do you think players and coaches watch it, or are influenced and motivated by it, as well as referees. How much impact does it have on the game. Does it influence quarterbacks? I look to hear my conspiratorial inclination dismissed.
I guess there are maybe 15 people that participate here, tops; but, it is a question that bugs me, and I thought I would throw it out there.
I guess I will find out.
