If you were at all interested in the series on sports concussions I wrote over the summer (found here
),here's a great read
It's an article from the New Yorker, which is known more for its high-brow approach to city living than sports coverage, but hits the topic of concussions and head trauma in the NFL pretty hard (forgive that horrible pun).
The article goes into some detail on the ways the NFL and football supporters have tried to downplay in some ways what has been dubbed the concussion crisis, and the title of the article alone - Does Football Have a Future? - may set some people off. But it's not an anti-football thing. It's just an interesting chronicling of the direction the sports is headed.
There are some pretty interesting anecdotes in there, particularly about how the forward pass was introduced to reduce injury at the line of scrimmage and, decades later, is now the same play responsible for the majority of concussions that now come through WR-DB hits (although, it should be noted, the dull, repeated hits linemen take are just as bad).
If you've got some time (this thing is 10 pages), it's definitely worth the read.
