Don't blow through any TV timeouts! Talk with the red hat before the game & make sure you're both on the same page regarding his signals.
Encourage your crew to stand at "parade rest" during these TO's. Nothing looks worse than seeing officials with hands-on-hips, or arms crossed "I'm bored" posture.
When making penalty announcements, get completely stopped, look up to the press box, s-l-o-w down, and wait a second after the announcement before going to your position.
Have fun!
