Yea, this trend is not looking good for football's long term future. I think the next step will be shock sensors in the helmets. After calibration there will be a mandatory concussion check after a specified shock, and a mandatory removal from game after a specified higher shock level. The levels might change if a player has had a concussion in previous weeks. Doing this would prevent players from 'playing through' concussions, reducing the chances of injuring an already injured brain.
Unfortunately, while improving long-term health, the knowledge of how much damage players are doing to their brains during a game may wind up scaring even more players off.
