Back in 2000 we tweaked the KOB rule that used to read : " foul...if LAST TOUCHED by K" . This allowed a kick that was muffed by several opponents and was last touched by K before OOB to be a foul. With the new rule came a lobster trap full (colloquialism for : "a lot of') new cases. One such showed (S & I) and told (case book) of a R player straddling the sidelines and catching the free kick. The ruling then was : "If the airborne kick had broken the sideline plane when touched, it is considered KOB; if not, it would be R's ball there touched." That case, as many accurate cases, have since disappeared as 20-30 new cases are added each year and we don't want a case book the size of NYC phone directory. IMHO, giving the ball to R at the spot of the touch without KOB or IP flags would be the fairest way if the OOB contact was unintentional.
Ralph, I believe you are referencing the following from 2007 (and others) CASE BOOK;
CAUSING FREE KICK TO BE OUT OF BOUNDS6.1.8 Situation C: (selecting only example "b")
R1 is running near a sideline as he attempts to catch a free kick in flight.
R1 has (b) one foot on the sideline, when he reaches through the plane of the sideline. The ball bounces off his hands and lands out of bounds.
RULING: (b) since R1 is out of bounds when the ball was touched, the kicker has caused the ball to be out of bounds.
The problem with this example is that it does not say which way R1 is reaching and what side of the sideline the ball is when it is touched.
If R1 is oob and reaching into the field of play, then I maintain the kicker did not cause the kick to be oob.
If R1 was reaching for the ball after it crossed the sideline the kicker did cause it to be oob like the Case Book example.
Does it matter which side of the sideline the ball in flight is when it gets touched?
