You seem to have this over inflated view of yourselves, thinking because you enjoy working on such a large scale stage, that somehow your opinion about everything matters. The NFL realizes the importance of its “image” so it has rules that specify the clothes and insignia you can wear, the language you use, and your “antics” after a touchdown or other “great” play. But somehow you and your employer don’t seem to care that you disgrace the entire nation and its 320 million people in the eyes of the world by publicly disrespecting this country, its flag, and its anthem! The taxpaying citizens of this country subsidize your plush work environments, yet you choose to use those venues to openly offend those very citizens.
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.
