Quote BrisbaneRhino="BrisbaneRhino"The stuff I've seen on the sort of problems Hohaia is facing seem to suggest its all about the cumulative effects of multiple head knocks rather than any single big hit. I saw a documentary which said a minor headknock which causes brain swelling without necessarily any of the symptoms of concussion being followed up by another hit was worse than a knock which obviously causes concussion because they latter aren't generally followed up (players being taken off etc).
In any event this isn't like a single incident can be directly linked to Hohaia's problem.'"
There are different issues you have conflated a little. A lot of the issue brought up in the NFL is CTE (Chronic Traumatic Encephalopathy), which is caused by lots and lots of small head knocks rather than a single hit. This is more like punch drunk boxers have.
Hohaia has retired because, according to him, he is suffering from PCS (post-concussion syndrome) which is far more likely to have actually been caused by a single incident of concussion.
Just as an aside, Saints receive no benefit to Hohaia retiring from injury compared to him just retiring, so unless we are possibly accusing them and Hohaia of insurance fraud, im not sure why this would be said if not true.
edit: just to add, there isn't really enough info in the public domain at the moment for us to know whether or not it was the flower incident so no need to jump to conclusions. However the statements put out and reaction does seem to be pointing towards some form of legal action by Hohaia, whether this is regarding his insurance payout of action against Saints, the RFL, Wigan, or Flower I have no idea, but saints reaction especially does point towards something happening next.
