Indeed, the man whom ESPN would later find a "violent, combative player known for his short temper" inspired the league rule against throwing a helmet after having done so himself to an opponent's helmet.  Peter Alzado, Lyle's brother, later identified the years of their youth—marked by an absent, alcoholic father and an over-worked mother—as the crucible for Alzado's unremittingly fierce style of play. "That violence that you saw on the field was not real stuff," his brother held. "Lyle used football as a way of expressing his anger at the world and at the way he grew up."  Defensive end Greg Townsend , a teammate on the Raiders, contended that the savagery for which Alzado became noted represented only part of a "split personality." "Off the field," remembered Townsend, "he was the gentle giant. So caring, so warm, so giving." 
Return to play should be prohibited if there is loss of consciousness, symptoms lasting more than 15 minutes, recurrence of symptoms with exertion, amnesia, or a history of prior concussion. Classification systems for concussions are not based on scientific evidence and advances have included neuropsychological or balance evaluations. These tests are more helpful if baseline data is collected on athletes before they are injured for a set of normative data for each individual. Therefore, a low baseline neuropsychological test would be the athletes standard for comparison and not solely be a reason to disallow return to competition.
The review article by Wojtys et al is a special report of the findings of the 1997 Concussion Workshop, sponsored by the AOSSM, and gave 9 recommendations for improving diagnosis, treatment, and return to play guidelines for athletes with head injuries.
An additional reference by McCrory et al from 2008 is added which describes more recent stricter recommendations regarding return to play. In general, athletes should not return to play the same day after any concussion.
Of course I knew that. But you missed my point. The commentor has LenBias34pt as his handle in here. Bias died after having used cocaine “for the first time” (if you buy that).
The commenter’s point was we should all clam up about athletes using PED’s or quit watching.
My point is, it’s ironic he’d choose Bias’ name as his handle since that young men died the way he did. Illegal drug usage is a huge problem in sports and society today, regardless if it’s PED’s or cocaine.
If we buy this commentor’s logic, should we ignore cocaine usage too? Should we just let them do what they want and only concern ourselves with what happens on the field? Maybe we should have beer on the sidelines and in dugouts instead of Gatorade!
The thing of it is, regardless of what another commenter responded to me about PED usage, some athletes do make the decision to use it because they know others are doing it and they know they do not have a level playing field trying to compete with them.
Think about it — your grow up dreaming of playing in the NFL, but you realize that some of the guys you must compete with are juicing and have a distinct advantage over you. That’s a tough decision for any young person to make.
There are documented cases of high school kids dying because they loaded up on steroids trying to compete at that level.
Here’s the deal. We know chemists are going to continue to come up with more drugs which have muscle altering effects. Are we going to stand firm and try to keep them out of sports, or are we going to cave in as we are doing with marijuana and just allow them to be used? That’s the ultimate reality.
I am firmly on the side of keeping them out of sports. It might be impossible to do it, but to me, it’s definitely worth the effort.
Growing up in the 60’s, I watched women from East Germany competing in swimming in the Olympics and they looked like they were football players — men football players!
Several years ago a documentary was made where they went back and found many of those women. It turns out they were being injected without their knowledge in many cases and had no clue what it was they were being shot up with. Many of them were in their teens at the time.
The results were astonishing. Many of them became sterile or lost babies after getting pregnant. Some had died very young. They had lots of medical issues.
It was clear had they had it to do over again, they would not have allowed their bodies to have been abused that way, had they been able to stop it. It was a sobering look at the cost of victory and I highly recommend it to anyone who can see it.
