Tight End illegal shift/ False Start

[Theisey]

quick movement out of a three-point stance by a back is potentially a false start if you so judge that's what the back did.
I've seen it called many times at both the NF and NCAA level. It's a judgement call, not a looking for trouble call. I could care less what the defense does. If I or teh calling official feels it is a missed snap count movement, it's a false start.
