With all of the injuries to the head that have been occurring in sports like football and hockey, the people who run it have been trying to make adjustments that a) make it safer, and b) still keep the people with the money happy. It seems that all they've managed to do so far is piss everyone off.
Quite frankly, I don't know what the answer is - but what I'm quite sure of is that all of the people who speak of "the good old days" and how we should get back to that time are somewhat deluded. While I'm sure that the number of head injuries was lower, the way that the sports were played was different - on top of which, I suspect a number of players actually were concussed, but nobody realized it.
The bottom line is this: the players are not going to get smaller, or slower. The equipment is not going to become less protective - so the games themselves have to change. We can wax nostalgia all we want for how it used to be - but if we don't find some way to adapt, then the sports we love so much are simply going bet themselves into extinction.
