2 dead ball fouls on scoring play
 

A1 scores a touchdown and is called for excessive celebration. Immediately following that, team B coach is called for unsportsmanlike conduct. Penalty options for both teams?

First, let's clarify that these DB fouls are AFTER the scoring play, not during it.

Team B can accept the 15 yards against A on the PAT or the free kick. That choice must be made before Team A is asked concerning Coach B's penalty.

Team A can accept half the distance on the PAT or 15 yards on the free kick.

Of course, either penalty can be declined.

Agree. The smart choices would result in an apparent offset, assuming no other penalties are involved.

I think the choices would depend on the specific game situation -- score, time remaining, kickers' abilities, return game, maybe even weather conditions.

For example, B chooses to penalize A on the try. If A's coach has confidence that his kicker can hit a 25-yd XP, they might choose to kick off from the B-45 rather than have the try from the 3.

That's why coaches get the big bucks!

"Immediately following" I take to mean too soon to have started enforcement, but too late to be simultaneous?

Yes, both fouls were dead ball fouls, but CT1 brings up a good point, one that actually occurred. Granted, the second penalty option would depend largely on the first by the opponent, but I explained the options to the captains and after giving the proper signals. I made the captains decide. The coach of A 'lost it' because I didn't come and explain the penalty options to HIM and let HIM decide what to do.

As a general rule, it's best to get the coach involved if there's an unusual penalty situation like this... I know it's not required by rule, but it's a good game management.

And here's the thing: If the fouls are simultaneous, the penalties would offset; however, if the fouls are separate actions (as Robert Goodman alluded to), we administer them separately and in order of occurrence.

So, if they're "separate actions", you have the following possibilities:

1. B takes A's penalty on the try (moving the try to A-18), A takes B's penalty on the try (moving the try to A-9). The kickoff is at B-40 as normal.
2. B takes A's penalty on the try (moving the try to A-18), A takes B's penalty on the kickoff (Moving the kickoff to B-45)
3. B takes A's penalty on the kickoff moving the kickoff to A-25. A takes B's penalty on the try, moving the try to B-1 1/2.
4. B takes A's penalty on the kickoff, and A take's B's penalty on the kickoff, leaving the try at B-3 and the kickoff at A-40.

Most likely, you'll end up with #4.
