Fantasy football also ruined football for me while I was playing it.
I agree that it made every game watchable coz either I had a player or my opponent did and if not that, maybe another fantasy game was in the balance. Every NFL game became relevant!
Over a few years, this turned into every NFL game became a source of irritation, angst, anger and rage for me. My Sundays were spent yelling at the TV when some dip**** would get tackled on the one or some dumbarse coach would call a pass on 1st and goal from the 1 with my tailback waiting for the handoff. Or maybe a td to my receiver would get called back on a phantom holding call.
The worst though when I was forced to root against certain players on the Pack. "No Favre! Hand the ball off instead!" "No Brooks! Get tackled!"
I was the commish and I also won my league twice (and about $800) and I still got fed up with it. Quit about 15 years ago and don't miss it a bit.
It's beyond stupid that it's covered on SC and sports radio.
