Kill the Holder!

[Warrenkicker]

I would agree with that.

But...
9-4-5 Running into or roughing the kicker or holder. A defensive player shall neither run into the kicker nor holder, which is contact that displaces the kicker or holder without roughing; nor block, tackle or charge into the kicker of a scrimmage kick, or the place-kick holder, other than when:
a. Contact is unavoidable because it is not reasonably certain that a kick will be made.
b. The defense touches the kick near the kicker and contact is unavoidable.
c. Contact is slight and is partially caused by movement of the kicker.
d. Contact is caused by R being blocked into the kicker or holder by K

So the player becomes the holder once he controls the ball on the ground and the ball remains live if there is another player in position to become a kicker. So based on 9-4-5 it is technically illegal to tackle the holder before the kick is made as long as the player is still in position to make the kick. I don't believe that is what the writers want the rule to say but it does.
