If Marion Barber's mental faculties and condition are declining, what can anyone do about it? From what Dez says, it is a deteriorating situation akin to Alzheimer's or another form of dementia.
It is easy to make the CTE connection with players like MBIII, Marshawn Lynch and maybe even Elliott if he plays long enough and continues to initiate contact to the upper body. MBIII was a player that the first word I would use to describe his style was violent. I wonder if he wouldn't get flagged in today's NFL because he used that helmet like a battering ram at times.
One thing makes me wonder about him prior to being a Cowboy. Remember when Garrett took over and the very first thing he installed was the dress code? Who was the one player to ignore that and I always wondered why nothing was done. Maybe they knew he was a little different and really didn't mean it as disrespect? So much of mental illness affects the brain's ability to process information, I wonder when his challenges first surfaced. I would bet that was well before he got to the NFL.
