Al,
Don't you think they should have left well enough alone? The NFL was far and away the most popular sport in the United States, and its tried and true combination of strength and speed, brutality and grace, and, above all, balanced play between offenses and defenses, made it the best product to watch on a week to week basis from the 1970's through around 2004. Great teams were built on tremendous defenses (1985 Bears, 1986 Giants, early 2000 Patriots), great offenses (1990's Dallas Cowboys, 1990's 49er's, 1999 Rams) and most often a combination of greatness on offense, defense and special teams (1980's 49ers, 1990 Giants, 1980's Raiders, more recent Patriots Teams).
I used to watch every televised game, all day Sunday and Monday Night. Now, with the watered down rules and "parity" I find myself only watching the Giants and catch the highlights (or lowlights) on Sports Center. The NFL has become the No Fun League, and frankly, with the officiating determining every game with subjective interpretations of ticky-tack rules, like 50 yard pass interference penalties, or a defensive holding in the backfield away from the play (a nicely defensed broken-up pass) turning a fourth and 19 into a first down on a touchdown drive, I have lost interest. I am starting to watch NHL Hockey, for a tough fast moving sport where the game at least resembles the sport I played as a kid.
