I remember when they outlawed hitting a defenseless receiver. That was just football we said. A WR in the air and the ball ten yards above his head...the safety was always taught to make sure he didn't get up for daring to go over the middle.
I remember when they started to enforce launching head first over the pile in the name of a block right after the whistle when a play was clearly over, but the objective was to take the top of the pile. That was football and meant to slow down the pursuit and gang tackling. In reality, it was to injure and we knew it. And we did it.
I remember when driving the QB into the ground with your weight plus momentum, not to mention with your helmet in his ear hole, was not only allowed, but expected.
I admit that I still don't understand targeting at times.
But here is the thing, and there is no getting around it. After playing football for a long time I know guys who are still not the same after playing with me in college where all this was part of the game. I know somethings at age 50 can be fuzzy and they say 50 is the new 40...not for some. None of us went on to make a living in the game and the bravado that was fulfilling does not heal the brain from countless times it hit the skull. It you played in HS and you say a 170 pound kid with marginal ability rocked your world during a play, but thats the game and you need to shake it off, you don't understand the big picture any more than I didn't when I did all the above tactics. The science is scary and yes, the game will never be the same. Get used to it.
