Ridell's system would basically be logging the intensity and frequency of all significant impacts to a player's head during games AND practices. The fact is that this system was accepted by a dozen or so teams, but ultimately nixed by the NFLPA. It wasn't until all the lawsuits and widespread publicity that the NFLPA all of a sudden came to the forefront of the picture, not the least reason being that the NFLPA could potentially face legal liability for traumatic brain injury, for its failure to protect its own membership.
