universally understood - if you touch the ball on a kick the kicker interference (roughing/running into) is gone.

does it matter if i touch the ball and my fellow linebacker is the one that runs into the kicker?

From the NFHS 2009 Case Book---
9.4.5 Situation A
K1 punts and R1 touches and partially blocks the kick. R2 does not touch the ball, but firmly contacts K1.
RULING
If R1 partially blocked the kick near the kicker/holder and R2 was near the kicker/holder at the time R1 touched the ball and R2 had already started his charge at the time the kick was touched, there would be no foul as a result of the contact by R2, unless it was unnecessarily rough.
COMMENT
The defense is responsible to avoid the kicker/holder whenever possible. In any situation, if the defense is to be excused for contacting the kicker/holder as a result of touching the kick, the ball must be touched near the spot of the kick. A defensive player may not, even after the kick has been touched, stop and then renew his charge into the kicker/holder, nor may he change his direction and charge into the kicker/holder after the ball is touched. Touching the kicked ball is, in itself, not license to charge into the kicker/holder. The defensive player will not be penalized if he has made an honest endeavor to block the kick and has either succeeded, or so nearly succeeded that he touched the ball and in doing so finds himself in a position where he cannot avoid contacting the kicker/holder as a result of his effort. The rule does not specify that only the player who touches the kick is excused from contacting the kicker/holder, rather it states, "when the defense touches..."

thanks

i was shooting cheerleaders so i only saw it but the umps missed it big time. 3 players had a shot at the block, the one from the holders side touched the kick and the one coming from the other side made contact. the one up the middle stopped short of the holder

just glad it didnt make a difference
