While googling around I found this article cut from the IBJ about a local automotive company turning it's interests to creating a better NFL helmet. The owner claimed even last year to be able to create a helmet 10 times better than current standards. Austin Collie has said to of been working with this manufacture and has been quoted saying "That's for him to comment." When asked directly about his new helmet he's been wearing in practice. Chip Ganassi racing is rumored to be financing this new helmet according to this article. The two biggest obstacles to getting a new helmet into the NFL is getting it though the red tape of the NFL's Helmet Certifications, and insurance which the Local Manufacture has very extensive experience from the automotive world.

Anyway, Take a look at this article. I found it interesting.
Best of Luck to AC, We love you man!
