To change the scenario, lets say that B26 commits DPI against A80, but A80 still catches the ball and scores a TD. After the score, A80 then taunts B26.
The penalties could be enforced at different times, with B taking the penalty on the try and A on the kickoff (or vice versa), right?
Without a microphone, that would probably be fun to try to communicate to the PA guy in the press box.
Yes ,A would choose first, followed by B's choice. Possibilities :
A wants B's penalty on PAT; B wants A's there,too = PAT @ 16 1/2.
A wants B's penalty on PAT; B wants A's on KO = PAT @ 1 1/5, KO @ K's 25.
A wants B's penalty on KO; B wants A's on PAT = PAT @ 18, KO @ R's 45.
A wants B's penalty on KO; B wants A's there, too : PAT @ 3, KO @ K's 40.
This is as it was with "dueling DB fouls" until the rule changed this year. You can thank us for that.
Possible explanations to PA:
"After the smoke cleared, it is what it is...you don't need to know any more."
or,
"Both penalties are enforced and by their captains' elections, the PAT will be at the ______ and the following kickoff will be at the ______________.
