I give tthe signals. Both on the goal line and as a Referee. First off that's the proper mechanics per the book. Next as any R can tell you the worst thing that happens to him is that he doesn't get the information. All you are doing when you signal a TD is that you are saying that the ball crossed the goal line. That's all. The R then checks with ALL the crew to make sure that no one has any issues. And then he signals the score. This doesn't have to happen immediately. If you have one of those games where there may be a problem then you use the scan of the crew to check for those types of problems. I have seen that most dead ball problems occur fairly quickly after a score (Most problems actually start BEFORE the dead ball). So taking a few seconds before giving the signal will suffice to making sure you're not going to have a battle.
