What in the world is an inadvertent signal? That sounds like something the average fan in the stands would come up with.
Well sorry Rulesman that I'm not a Refstripes Hero!

Excuse me! I was just using the same (admittedly) awkward terminology that Kalle had used previously in the thread. Oh, but I suppose he's a Refstripes Hero so why bust on him?!? Inadvertent signal, early signal, you're the expert, you tell me what to call it.
As for when it becomes an early or inadvertent signal ... I'm not sure, but there's little doubt he's signalling early. It supports the very different actions of the official in the UH v SMiss game yesterday who was criticized (IMO wrongly) for waiting so long to make the call.
