When watching the game against Ireland I couldn't believe the size of some of the South African players. Even their halfback de Klerk is built like a little tank.My rugby theory
Hypothesis – unless rugby heads down a different path, rugby players will keep getting worse head injuries, and rugby, as a sport, will peter out
Fact 1 – Rugby players are getting bigger. More muscular. Fast twitch = faster. Weightlifters. Less aerobic. No more Michael Joneses / Terry Wrights / Josh Kronfelds. More Papalii’s, Canes, etc.
Fact 2 – Rugby has a problem with head injuries and is trying to clean it up via cards
Fact 3 – Rugby is a collision sport, and head injuries are more a function of steep changes in acceleration at collisions, than infrequent head highs, i.e. making a countless tackles and hitting rucks at full pace are worse, over a career, than getting hit high on occasion (this was told to me by another parent (a doctor), whose mentor is a US neurosurgeon, researching brain trauma in the NFL)
Reasoning –
1. Dangerous play will keep getting pinged, slowing the game down
2. A game with more stoppages increases the value of bigger players that don’t need to be as aerobic as they did when the game flowed more
3. Bigger players = bigger, faster collisions = more head injuries
4. So perversely, the focus on pinging head highs is actually making the head injuries worse
It was often thought league used to be bigger players vs rugby. The sports have swapped places as league has been sped up and rugby slowed down (and body shapes have correspondingly swapped places). It only takes 5 mins of watching the RWC to see the stark difference from the NRL, in terms of body type and stoppages in play
Conclusion - rule changes that make the game more aerobic will reduce body size, which would be a more effective solution to brain trauma than pinging dangerous play
