I have blogged aabout head injury and football several times. What a former player and now former TV football analyst,Ed Cunningham had to say has much more limbic valence.
I refer to what he wanted to say to some football coaches after one of the more meaningless post season Bowl games after watching one the QBs being repeatedly pummeled.
Paraphrased - Dudes, what are you doing- these are just kids.
addendum 9/4/17 Another quote I had to add. This from a George Will column regarding NFL football. He quotes college football coach Jim Harbaugh who said [football]" is the last bastion in America for toughness in men". Will added ..that thought must amuse Marines patrolling Afghanistan's Helmand province.
