From the NFHS Basketball Preseason Guide 2007-08:
“In the past, a common interpretation has been that any touching of a dribble by a defender ended the dribble,” said Mary Struckhoff, NFHS assistant director and editor of the NFHS rules book. “However, the language in our rules implied that the touching had to be by the hand and had to be intentional. The change in language [of the official rule] provides consistency with the current enforcement of the rule.”
Participants in rapidly evolving regulated industries would be wise to ponder the above statement.
