Could new helmets reduce concussions? How the football world is trying to tackle the problem

In this year's Super Bowl, Philadelphia star offensive tackle Jordan Mailata is hoping a new generation of helmets will help keep him in the game — avoiding the same fate as Buffalo Bills cornerback Christian Benford, who was sidelined after suffering a concussion in the AFC Championship weeks ago.

"Headbutts are common, they're going to happen," Mailata said. "It's what happens in the trenches."

Neurosurgeon Dr. Allen Sills, chief medical officer for the NFL, is helping lead the effort to reduce concussions.
