If you want to make your answers unequivocally correct, in 1 and 4, add the time, qtr, and score to highlight Team A does not have the option to start on the snap per 3-4-3-b.
In 5, Team B may have that option inside 2 minutes in the half.
That’s why every question ‘setup’ should include time and score. Every question I author does. I can’t seem to get that across to other folks that offer questions.
Every question should follow the format that we learned from John Adams decades ago:
Down/distance, yard line (succeeding spot), [lateral position optional,] time remaining (period), clock status, play clock time remaining(duration), Team A score, Team B score.
(Note: I added the play clock time and status, because the 40-second play clock came about after Mr. Adams retired from NCAA involvement.)
2/5, A-40, left hash, 5:30 (2), ready, 32(40), A=14, B=10.
This tells us everything we need to know. Note that Team A ALWAYS puts the ball in play, so there is no need to list “A” at the start of the setup statement.
Then you describe the action as thoroughly as possible, using RULE language:
After possessing the snap, A10 attempts to hand the ball to A23 at the A-38. A23 muffs the ball, which falls and deflects off of A23’s knee and bounds toward the left sideline. Players of both teams attempt to recover the ball, with no player gaining possession before the ball rolls out of bounds at the A-42 at 5:25 (2).
Ruling:
The ruling should follow a similar format (but the team that will next put the ball in play is included), with thorough rationale, using rule language, as needed:
A, 3/7, A-38, 5:25 (2), ready, 40 (running).
The status of the ball after the muffed handing attempt is a fumble. When the ball rolls out of bounds in advance of the spot of the fumble, the ball belongs to Team A at the spot of the fumble, for the next down, and, by rule, the game clock will start on the referee’s signal. The play clock is set to 40-seconds and started when the ball becomes dead at the end of second down.
[Note: A learning point with this example is that, even though the spot of the fumble (end of A10’s run) has no importance for penalty enforcement, it is necessary to mark the spot of the fumble with a spot marker (bean bag), in the event the ball should go out of bounds in advance of the spot of the fumble. Also, if this were 4th down, and a teammate other than the fumbler catches/recovers the ball, the 4th down fumble rule applies, and we’d need to know the spot of the fumble.]
