Conflict of interest is obvious with physicians hired by franchises. Now are they sports skilled physicians? Or their specialty in neurological tissue damage a top skill? Is field testing done with best diagnostic devices or left to off-the-cuff impression? Brain damage lasts a lifetime. Why take risks when an injured player could  prevent further aggravating brain damage? Franchises`owners see same day win or lose. They cares little about a player`s future. Money is the master here.
