Yes. The NFL should be worried. No. It is still going to take a lot of time. However, with a report confirming that CTE has been confirmed within the skull of a live person, people need to start getting concerned. Oddly enough, add a dash of hope in that emotional cocktail as well.

Pople who want to know the risks, and when those risks start to become to crazy, are about to receive some good news.

From the Chicago Tribune:

Dr. Julian Bailes, a NorthShore neurosurgeon, said Wednesday that confirmation has arrived.

In a paper published last week in the journal Neurosurgery, Bailes and other researchers reported that one of the former players who underwent a scan had his brain examined after he died — and sure enough, the tissue revealed he had been suffering from CTE.

This isn't all bad, as Bailes did mention a positive that comes out of this in regard to how it could help the NFL.

“If there’s ever a treatment developed, you can test the response to it,” he said. “If you can trust the scans, you can tell a football player he shouldn’t keep playing, or tell someone in the military he can’t (be exposed to) explosions.”

If a treatment can be found, then tested (with it working), this could ease a lot of concerns people have with the violence happening on football fields at all levels. That being said, we're just finding out that scientists can find CTE in a person. We're probably some time away from those folk finding a cure or even just a treatment.
