I used to, but its been a few years.
Here's my basic spiel, though, if it helps:
"Hey guys, thanks for coming down. I know this is probably kind of repetitive for you and I know you have probably been working the clock here for years. I just like to make sure I get to see you in person and you get to see me. Every crew kind of does a few things a little different and I just like to make sure you're familiar with our crew's process"
(I do this because they ALWAYS have one guy who says he's been running the clock for X years. This makes it to where he's receptive because I'm not criticizing HIS work, I just need him to learn our process)
Clock guy
-------------
I have 5:32. When you get up there and you set the clock for the last time, make sure it ends 3 mins before 7:30
Each Q is 12:00(in HS)/15:00(NCAA). When the 4Q is over, your job is done.
Turn off the auto-horn. If you are operating the down/distance/score as well as the clock, the clock takes precedence over anything else.
Be slow to stop the clock and quick to start it. If a player goes OOB or is tackled or scores, let the clock run for one "Mississippi" and then stop it. When the ball is snapped, do it as soon as you see the ball moving backwards. If you know the R is going to wind the clock, have your finger on the trigger and start it ASAP.
Clocks stop on the following:
OOB, INC, Penalty, Score(any score, FG, TD, SFT), all kicks, timeouts(both officials and team).
At halftime, put the clock at 24:00 and do not start it until you see our R in the EZ winding it.
DO NOT LEAVE :01 ON THE GAME CLOCK EVER!!!!
Play Clock guy
-----------------
Assume the play clock will always be set to 40. There are only 8 instances where it will go to 25:
*Start of every new quarter
*Punts <--This is one I have to change this year
*Changes of Possession
*Penalties
*Offensive Helmet off
*Defensive Helmet off
*Timeouts(Official and team. This includes measurements)
*Scores that aren't a TD <--This is one I have to change this year
On regular scrimmage plays, when you see an official kill the play, count "One Mississippi" and start the clock. On TDs, count to "Three-Mississippi".
If the play clock runs out, DO NOT reset it to 40. Just leave it at 0. I dont mind if you dont reset it again until the ball becomes dead, just to be safe.
Try not to run the play clock under 40 seconds or 25 seconds.
Look at me the whole game. If there is an issue where we need to change the play clock, I will raise either one hand(25) or both hands(40). If you dont see me, look for the white hat doing it as well.
