personal away from the ball

[cad]

Sorry, but I misread what had occured. There was personal foul behind the ball before it entered the endzone. I would penalize according to the "all but one principle" and penalize 15 yards from the 30 yardline. If this penalty occured after play was blown dead, there would be a penalty administered from B3. If this was a taunt by A or any other unsportsmanlike penalty, this would be live ball foul but administered from the succeeding spot.
I had a situation a few years back where a back was running for a TD and a teamate decided to taunt an opponent. Penalty flag was thrown and offended coach of B argued that TD should not count and we should penalize from the spot where foul occured. We ended up penalizing on the try, B3 abd 15 yards back. If I'm overlooking anything get back to me.
