Concussions

Here's something I find curious and wish some intrepid reporter would look more into - hopefully the NY Times which has helped raise national attention about the problem of concussions in the NFL and all professional sports.

To wit, how is it that NHL players like Sydney Crosby and now Chris Pronger are losing entire seasons to concussions and yet not a single NFL player misses more than a week or two? Is there something about the hits the hockey players take that are different than football? Is it related to the head protection each wears? Or is it a different culture among the players wear NHLers aren't afraid to speak up while NFLers hide concussions?

It's worth exploring further.
