The guy that runs our Back Judge meetings is also a college football official and he was telling us that on pass interference penalties they have to provide the type of pass interference, I don't remember the exact terms he used but they were along the lines of
DPI:
- Early Contact
- Playing Through the Back
- Grab and Restrict
- Arm Bar
- Cut Off
- Hook and Twist
OPI:
- Blocking beyond the expanded NZ
- Pick Play
- Creating Separation/Push Off
- Playing through the back
Personally, i'm trying to do this in my (HS) games. Is this something any of you do?
