NCAA Rules: Learned this from a coach last night.
Player coming in to block kick right up the middle, and has it blocked dead, but spreads his arms in the air and somehow manages to miss the block, landing on the semi-airborne defenseless punter, cleaning his clock. I flag the most obvious and textbook RTK I've seen.
Coach screams out, "You can't call that! It's not a penalty if he's GOING FOR THE BLOCK."
Ugh.
