crackback blocks

[aoaoffish]

I can speak from experience. In high school I was an outside linebacker, I was crack blocked all the time. I would estimate that 50% of the time it was an illegal block. It seemed like when the receiver wanted to crack block, it was either on an option or sweep to my side, my first reaction was to head upfield to tackle the pitch man. As I'm running away from the wide out towards the ball my back would be exposed to the wide out, he either opted to not block, or block me in the back.
