There is just too much Football.
The NFL has turned itself into a year round show biz empire.
I just don't think there's enough people that want MORE games extended nearly throughout the year...... I don't. I have a season for watching and then it's on to other things. The anticipation of the next season is a good thing...... its not a regrettable void.
I've always felt that even the additions of Thursday and perhaps Sunday night football was of dubious value.
Humans are always subject to burn out. I know that not everyone feels the same way I do. But clearly there's not enough folks who'd prefer nearly no end to the games in order to support another league and the quick demise of the AAF is evidence of that.
