Clearly a move designed to cause B to jump into the NZ. I can only assume the snapper didn't think B were in the NZ, so he didn't snap. But, the A coach was clearly expecting that result, since he ended up calling T/O, when he didn't get it. The team was't prepared to run a play otherwise.
False start. We need to make these calls to nip these things in the bud, before they become full-blown thorn bushes.
