Roger Goodell wants to ban the three-point stance. Short version: doing so would possibly limit the number of powerful blows a lineman has to absorb, decreasing the possibility of debilitating brain damage later in life.
Spin: nice idea, but because Goodell isn't doing anything about other serious problems in football (serial cheap-shot players like Ryan Clark and Ray Lewis), it's possible this won't make much of a difference, and thus it's only a PR stunt.
I link to the Football Outsiders post to show the discussion ... sadly, there are several people who seem to believe that the players know what they're getting into, therefore, screw them, we want our violence. (You know, the NASCAR-wreck crowd.) This guy retires with 10 concussions and develops Alzheimer's at 40, but who cares? Look at this rookie? Wow, he's a really big hitter!
It is the internet, and thus e-pinions are likely to be stronger than you'd see in "real life", but still, it's discouraging to think that on a statistically-inclined football site, there are a number of people back in the Coliseum, still rooting for the lions. (Ha. Maybe that's Detroit's problem. There isn't a team of Christians.)
