More than two decades ago, the NFL started to compile research on the effects of head injuries around the league. It formed a committee back in 1994 and, ultimately, released a report, which it said accounted for all concussions diagnosed by by team physicians over a five-year period up to 2001. But this morning, the New York Times released its analysis calling that study "deeply flawed. "The article says, "For the last 13 years, the N.F.L. has stood by the research, which, the papers stated, was based on a full accounting of all concussions diagnosed by team physicians. 

But confidential data obtained by The Times shows that more than 100 diagnosed concussions were omitted from the studies. The committee then calculated the rates of concussions using the incomplete data, making them appear less frequent than they actually were." The report says some of those omitted concussions included severe injuries to stars like quarterbacks Steve Young and Troy Aikman.

Executive Director of the Concussion Legacy Foundation,Chris Nowinski(@ChrisNowinski1), Founder of Sports Concussion New England, Neal McGrath, and Former NFL PlayerTim Foxjoined Jim on Thursday night to discuss. Nowinski said the most troubling part of the whole thing is that, "they knew they were lying the whole time and they just kept lying." McGrath, who works with teenagers, said that "concussion rates are so much greater than what those early studies showed." He said that concussion data missing for an entire season for a team, could not be meaningful data.

Fox, who suffered multiple concussions throughout his football career, discussed his current symptoms, such as memory loss and disorganization issues. He said that he and his teammates would "tough out" injuries, rather than sit out a game. As a result, Fox calculated that he's had over 50 concussions. He said if he could go back and do it all again, he would play football but do it differently.
