Bad break for Jimmy G. But, this gives a new perspective on questions about why the U has been recruiting so many OL candidates. Maybe the coaches knew more than they were letting on about this, and they were hedging their bets in case both Gjere and Campion were unable to continue their careers.
On a serious note - this concussion thing is going to have a huge impact on the sport of football. If the equipment makers and doctors can't find some way to give more protection (and it may be medically impossible), it really puts the future of the sport in some question. The NFL is facing all kinds of potential litigation from former players who are suing for compensation for their medical expenses. All it would take would be a couple of high-profile lawsuits and major judgements at the HS or college level, and all of a sudden you could see programs folding. I hope I'm wrong, but the possibility scares me.
I played for a while (I had one concussion while playing and never suffered any lingering effects) and now coach, and it is certainly an issue that is discussed at every level. The good news is that there is a lot of work being done in the area, and there are a bunch of folks who see an opportunity. Remember the old saying: "Necessity is the mother of invention."
First, techniques and rules have changed. People are aware of the risk, so the coaching has changed. Kids have been exposed to the risks, so they actually pay attention to this coaching in ways that previous generations never did.
Second, there are some pretty exciting equipment developments taking place. The idea is to change the basic helmet design, which hasn't truly been altered in 30 years. The main problem is the hard outer shell. In car terms, there is no crumple zone. Imagine a car wreck without a bumper that crumples. Even if there are air bags, the impact is still a lot harder. Right now, helmets are cars that have air bags but no bumpers to dissipate the energy. What folks are looking at now is making a soft outer layer on top of the hard shell in order to spread the energy around. Makes sense, right? You don't have to be a physics professor to know that dropping an egg on a pillow is a better idea than dropping it on the floor.
The crazy thing is that this isn't really new. Steve Wallace wore one of these a while ago when he played for the 49ers. My guess is that it never took off because people thought it looked silly. As awareness grows, however, it looks significantly less silly to me. The statistics for this new equipment is amazing, and as helmet technology continues to improve the shape, amount, and placement of padding on the inside of the helmet, work on the outside of the helmets will continue to progress as well.
Here are links to two of the companies who produce these products. The team I coach will actually be using the Guardian Caps this year for practices (they are not yet allowed for games). At this point, I can't imagine a school not using them for practice. They keep kids safe and prevent teams from losing players. Seems like a good idea to me.

This last one is the direction I think helmets will go. My guess is that the technology will eventually be licensed to one of the major helmet manufacturers. I don't think we are too far away from these happening:
