The snap is not imminent

[Reffing Rev.]

NCAA rules (but I want to hear NFHS too)

PAT from B's 3.
QB A1 after coming set in their normal shotgun formation moves up to the line calling out blocking assignments moving over behind the RG continually calling out blocking assignments (and remining in parallel motion). The snap then goes directly to back A2 who runs into the end zone.

I was U and after the play R, H and I discussed the play but we're not sure.
