The only intent in tackling, is tackling

Millisecond thought does not exist, nor has it ever existed

Even pretending to "convince" a player into saying "Yeah, I can foresee where my head will be in regard to the opposing player's head" is absolute horseshite brainwashing of that particular player. He's just telling some coach what the coach wants to hear.

What is the real thing that brainwashed player does? He turns his own neck sideways in an attempt to follow some bullshite coaching instruction against "targeting" and he puts the literal side of his neck directly into the path of the collision.

Spearing was always a penalty, and for good reason.

"Helmet to helmet" on the other hand happens every fricking play of every fricking game. Along the line, during linebacker collisions with offensive linemen or running backs, etc

But they only make a big deal out of it on open field defensive secondary plays because that's what the national narrative against the game of football has coerced refs into doing.
