Nice to see that more is being done in terms of helmets and safety research. Here is the link to the ESPN article by Gregg Easterbrook which can be found here:
Some highlights of the article:
"Duma further notes there is no correlation between helmet price and safety. The lowest-ranked helmet, the Adams A2000, costs $200, while the four-star Schutt DNA retails for $170. The DNA looks like the best value on the market -- nearly as good in safety ranking as the top-rated Riddell Speed, but costs about $75 less. This can matter if you're buying 100 helmets for a high school or small college."
"The NFL's data, and this study conducted at the University of Pittsburgh, suggest that advanced helmets -- basically the ones Virginia Tech found to be four- or five-star -- lower the risk of concussion by about one-third."
