[The Roamin' Umpire]

This is actually a surprisingly tough question. The rule the casebook refers to, 3-4-2b3: "The clock shall start with the ready-for-play signal for other than a free kick if the clock was stopped: ... b. Because the ball has become dead following a foul provided: ... 3. The action which caused the down to end did not also cause the clock to stop." The clock stops at the end of this down anyway(*), so 3-4-2b3 will not cause it to start on the RFP.

The counter-argument says that the clock cannot start on the snap, citing 3-4-3: "The clock shall start with the snap ... if the clock was stopped because: ... b. B is awarded a new series. c. Either team is awarded a new series following a legal kick." No new series is actually awarded here, so we can't start the clock on the snap, either. Now what?

The catch is the statement that I marked with a (*) earlier. 3-4-4 tells us when the clock should be stopped: "The clock shall be stopped when: a. The down ends following a foul. b. An official's time-out is taken. ..." The only reason the clock stops here is an official's time-out (see 3-5-7c). So the rule we really need to be looking at is 3-4-3a: "[Clock starts on RFP if it was stopped] For an official's time-out, other than when B is awarded a new series or either team is awarded a new series following a free kick." Since there is no new series being awarded (see 5-1-2), this rule tells us to start the clock on the RFP.

All that said, what I'd like to see is a rule that says straight out that fouls (other than delay of game) are ignored when considering when to start the clock on the next play.
