So finally watched the Frontline Documentary on this.
So apparently when Mike Webster filed for disability, the NFL had its own doctor interview him and that doctor concluded that Webster's mental issues were the result of repetitive head injuries sustained playing football. The NFL paid him disabilities. This is in 2000.
In 2003, the NFL starts publishing in the medical journal Neurosurgery a series of articles that state concussions are not serious injuries. They also claim that returning to play after a concussion in the same game does not involve a signifiicant risk of a second injury. These papers also suggested that it might be safe for college/high school players to be cleared to return to play on the same day as their injury.
The editor (Robert Cantu) of the medical journal objected to these articles being included and took his concerns to the editor in chief (Michael Appuzzo) who overruled him. One of the writers on the papers (Mark Lovell) admits that the data and research he conducted was flawed.
In addition, when Dr Omalu wrote a paper on finding CTE in Webste, the NFL's MTBI committee and its doctors formally asked him to retract his paper. They also claimed there was no evidence that Webster had any chronic mental problems that resulted from football (despite the NFL retirement board doctor concluding otherwise).
So what do we make of this. The NFL in 2000 concludes privately in Mike Webster's case that football caused his mental issues but then publicly in supposed respected medical journals is pushing the idea that head injuries are not a big deal and even going so far as to comment on college and high school players. They then attack a paper that publicly says Webster had CTE despite already concluding privately in 2000 that he did have mental illnesses.
Sure, no ethical, moral, or legal concerns here guys. Move along.
