I'm also having a hard time understanding the start the clock on the snap part of the Ruling to play situation 4. If the game clock is running and team A false starts, why are we going to start on the snap if the 10-second subtraction part of penalty is declined? Isn't that giving team team A what they want? Or because team B declines the 10 second subtraction part only if they need to get the ball, we start on the snap thus conserving time?
There is nothing I see in the new 3-5-3 that states that the clock starts on the snap if the 10-second subtraction part of the penalty is declined, so is this some weird reverse use of 3-4-3? In other words, team A is conserving time when they foul (intentionally or unintentionally), team B is OK with that because they want as much time as possible if they are going to get the ball back, so they decline the 10-second subtraction, then we start on the snap giving team B the advantage of team A fouling.
Yes, this is a use of 3-4-3, but nothing weird at all about it.
This is nothing more than we would have done last year without a 10 second subtraction. Last year if team A committed a false start under one minute and they would have gained an advantage by starting the clock on the ready then the referee would have invoked 3-4-3 and started the clock on the snap.
Here, if team B declines the 10 second subtraction, then they obviously want as much time on the clock as possible, which, under any plausible scenario, infers that team A would gain an advantage if the clock starts. Therefore, *ALWAYS* start the clock on the snap if team B declines the 10 second subtraction.
