While the clarification makes perfect sense as to how the rule really should be, I'd find it hard to call it that way until ASA changes it in writing. There are some rules-savvy offensive coaches out there (and some that are just plain offensive), and if I were to make this call, I'd think that they'd have ripe fields for protest.
However, I appreciate Mike's follow-up on this information, and I hope that ASA puts this in writing for all to see as soon as possible.
