LOD on 4th down

[ajmc]

IFP is considered a running play (as defined by 10-3-1, as opposed to a loose-ball play). That the play ended when the IFP hit the ground doesn't change that designation.

The basic spot for a running play is the "End of the Run (with the exception of an ABO situation) NFHS 3-4-3 determines when the clock starts with a snap, which does not include when a team gains a (continuous) first down (which is what this question is ALL ABOUT).

As suggested, when the succeeding spot left "A" behind the LTG, the "loss of down' provision of IFP would end the series for "A", starting a new series for "B" for which (according to 3-4-3) begins with a snap. Since , in this example, "A" earned a "continuous" new series, the clock starts on the RFP.

NFHS: 3-4-6 is simply not a relevant factor, in this scenario.
