BITS, I'm not quite sure how you came to this conclusion but I don't see how I'm vastly overstating anything. Using that mechanic to indicate a throw-in violation doesn't make sense. Please tell me when else during a game, and in what context, you would use that signal for something other than a travel?

I thought I only pointed out the obvious. You have an official signal a travel violation during a throw-in and you have a forum full of somewhat experienced officials that are arguing over what he called.
Doesn't seem real clear to me.
