Momentum...

I was introduced to the PBS Frontline presentation "League of Denial" about concussions in the NFL.  The subtitle - "The NFL's Concussion Crisis" tells you where they are headed with the coverage.  If you are invested in the NFL (you  make lots of money off it, or you really enjoy it as a fan) then this is hard to hear - and for many, easy to dismiss. If you are not invested in the NFL you probably wonder how anyone can miss the implications, and continue to support the NFL on its current direction (and lots of other sports that damage the fragile brain - I recently talked with a tearful mother about her daughter's concussion from soccer and the damage it has done still two years later).

Momentum.  The bigger the organization or the more you are invested, the harder it is to make a change.

How important is health?  What are we willing to give up to keep it? How high does the incidence of brain damage have to be in a sport to warrant a change?  How can we help people work against the momentum, when the momentum is on an unhealthy path?
