Who said its a sudden revelation? Its a point of fact that the NFL season is a meat grinder. 'Tackling', for the most part, has been replaced by high speed collisions akin to being in a car accident. To think that someone couldnt die on the playing field as a result of one them is just naive. IF that ever happens, this little discussion will be getting visited on a much more broader scale by people who legislate things far more important than what happens on a football field. ** shrugs ** All that said, the NFL doesnt need to expand to 18 games. Its fine at 16 but the $$$ thats at stake will make it all but impossible to keep it from happening.
