This seems to be the most inconsistent thing I run into for wing guys on how it's handled for different supervisors.
The mechanic that is being used in the ECFOA and CIP seems to be to punch back when a forward pass is caught behind the LOS. Backward passes are not signaled in any manner.
After going to several clinics, I see the Big 12, Big 10 (COC), and most other D1-A conferences punch back on backward passes only. They do not signal if a forward pass was caught behind/beyond the LOS.
I personally like punching backward passes. This way everyone knows we've made a ruling on that. Additionally, if we punch a forward pass caught behind the LOS, who are we punching for? The deep guys never look at it (I've been told) so why do we even do it?
What do you use in your area and what do you think is better?
