As TxMike points out, RR is interpreting that the spot of a pass is the point where the arm begins to move forward. Never heard that before, but I can live with it. I just wish he'd put it in writing.
Also, check play Number 4. This is the absolute CLASSIC example of what I've been preaching about for decades.
The play is ruled properly, and that is the bottom line. So, not criticizing any major ability to officiate.
But, watch the B. He's got his bean bag in his right hand. Just after the ball is muffed by the receiver he 'reacts' rather than processes, and tosses his bean bag. Technically, that means he's either got a fumble or the end of the kick, and we know that neither of those has happened. If he'd left his bean bag on his belt, and remineded himself before the play, "bean bag B possession or A illegal touch; tip signal if mufed by B; flag if KCI by A," then he might have just given the tip signal, telling the world correctly and more accurately that B has muffed the ball and he has observed that fact. What would he have done if he'd had KCI? I can almost guarantee you that he'd have tossed his bean bag first, then fumbled for his flag and tossed it.
There is a better way.
Your whistle, your flag, and your bean bag are tools. Know when to use them. Leave your flag and bean bag stored on your belt/in your pocket, and then select and employ the correct tool at the right time.
It may seem like a little thing, but this is something that could become a big thing. Besides, it is the little things that separate great officials from good officials.
