To the point of the league trying to limit dangerous and big hits, and the very mention of possibly getting rid of the kick-off. IMHO, the league has lost site of the core reason why we watch the game -- COURAGE -- this goes for both males and females.
The league has tried to gain a wider audience by making the game more high scoring and reducing the "violence" of the game to appeal to more females.
BUT, the very reason that football has such a huge audience -- and is different than any other team sport -- is that we admire the players because we know it takes toughness and courage to play the game; to play a game that risks big hits and injury. To go on the field against other superb athletes, tough athletes, ready to physically challenge each other for dominance on every play. And players have to be able to carry out their assignments while under the duress of phyiscal fatigue and with the risk of taking a big hit.
At what point is the game so watered down that the risks of injury so minute that it no longer takes much courage to play? At that point, it is no longer football, its soccer with plays, its basketball. And the die-hard fans that make football so unique, and profitable, dies with it.
