Player touches out of bounds

[William C]

OK - this is one situation --after calling for many -many ...... years -- I'm really not sure how to handle.
I know what the book says - but in reality - how are we calling it?
You see it called by the pros a lot -- but not seen / called much if any - in high school.

Player runs down the sideline and TOUCHES the sideline and continues inbounds and participates ------------

Player back to punt -deep in his EZ and before the snap - his foot TOUCHES the end line --------------

Just wanted y'alls opinions.
