You're right, on the sidelines. But it's more than just "how many fingers am I holding up?" or "what day of the week is it" after the initial incident.
In the days and weeks following...things like headaches, ability to concentrate, sleep patterns, etc are watched. Some guys get dinged and are fine in a couple days...others have ongoing symptoms (like Justin Morneau of the Twins). Even with advanced technology, what the patient reports is a key link in the assessment and treatment of any illness.
Regardless, I find it hard to believe that if a Dr recommended against Robinson playing...Ferentz would have played him anyway and put him at risk. That's the unspoken inference in this thread.
Yep, it is estimated that about 80% of every medical diagnosis is based on verbal information provided by the patient. This is why health communication is one of the fastest growing fields in social scientific research.
Sure, ARob could have said, he wasn't having headaches, that he was sleeping well, that he had experienced no instances of confusion, and that his academic woes were just a matter of him not taking school seriously enough. Beyond that, the 20% of the diagnosis based on neurological tests could have been inconclusive, which would have put the weight of the diagnosis firmly back to the information the patient provided during the interview.
So yes, Adam could have been concealing information about his condition, which, considering the fact that he came back after two weeks for a 6 week medical condition last year, would make sense. Also, the guy has have been conscious of the fact that basically everyone was waiting for somebody to come take his reps, whether that was Brinson, Hampton, Wegher, Coker, or even Rogers.
However, this does not change anything with respect to what his mother said. Perhaps the real information has come out now. The goal should not be to bash ARob or use him as an example for other players, but to maybe understand what ARob did for the program and have him spend some time with the neurologists at the UIHC to see if maybe we can learn something about his case, not only his sake, but also for future Hawk players as well.
