I think the whole regulatory effort to protect these young men from unnecessary injury is a work in progress.
And I think what makes this effort difficult is the obvious disconnect between the primal violence and manly man culture of the game . . . and our general 21st century enlightenment as to how humans, no matter how highly paid, should be treated.
Indeed, but the point I wanted to make to smack was that I don't think the NFL is worried about players who put butts in seats -- all they care about is quaterbacks, namely, Brady and Manning.
Case in point, 3 players sidelined that "put butts in seats":
Gronk - last year, dude torpedo'd right at his knees, ending his year.
Megatron - usually gets hit low too, re injured the ankle after a low hit in the Jets game. Missed 4 weeks.
Dustin Keller (not as good as the above) - ACL, MCL, PCL, and dislocated knee all in one hit from Texans DB that said because of the concussion rules, he's gonna "hit low", or something to the affect of taking knees out, blaming it on the NFL rules.
If they cared so much, they'd outlaw all torpedo shots, even low ones.
