One of the problems is that we can’t see how effective any changes are for decades. The examples we see today are players who retired in the 90’s or earlier. It will be interesting to see if the numbers reduce over the next 20 years to reflect the changes being made today. Balls are not as heavy as they were, especially in wet weather. Heading drills are massively reduced compared to the 90’s and earlier and it’s banned in kids football. There are also far less long balls and power headers than there used to be in games.
