First Touching or......

[PaulJak]

I'll give it a shot.

6-2-5 - ... If any K player touches a scrimmage kick in this manner (described in the first paragraph as first touching), R may take the ball at the spot of first touching, or any spot if there is more than one spot of first touching, or they may choose to have the ball put in play as determined by the action which follows first touching... (More stuff about R losing this right if R touches that ball and then commits a foul or any foul is accepted).

So since in this case, no foul is referenced, R has the option to determine if they want the first touching spot or to put the ball in play as determined by the action (which they wouldn't since it would be K's ball).

I'm sure people will site the rule about K being able to advance a kick recovered behind the NZ, but first touching occurred first and gives R the options on the action after that (so long as there are no fouls on the play).

Ruling: R's ball 1st and 10 from K's 15.
