I don't have the rules book with me, but I recall that even though this is called "interlocked blocking" in the rule book, I recall that the signal for the foul is listed as the "holding" signal instead of the "helping the runner/interlocked blocking" signal.
Just curious as to why the rule book has it this way, especially when they're using the term "interlocked blocking" ??? (not to say that rule book is never wrong)
