Well, I got roped into work the clock for a couple of game this year. It happens when you retire and they are really desperate for timers.
My gosh, R's some of you are horrible with signals. Take your time. Over exaggerate and go SLOWLY. My biggest issue has been when there is a helmet that comes off a player. Why do we rush to get the darned ready when the player isn't even off the field? Three times I had an offensive player with a helmet off and as they stopped the clock, the R is winding it while the player is picking his helmet up off the field. The offense twice in this situation got a DOG because the R started the play way too early. Slow the heck down boys. Watch, wait, and let your wing tell you when he's off BEFORE you give the RFP.
