In discussing hypothetical situations, the topic came up about whether or not a single action might result in multiple enforceable penalties. We quickly determined that it could realistically only occur when USC comes into play -- mostly because they'd have to be, at the very least, dead ball enforcement. If A65 held the linebacker B56 by grabbing his facemask, you cannot enforce both holding and the facemask fouls on the same play since they are both live ball fouls by the same team.
The "best" example we came up with is this: Assistant coach Jim Bob thinks he sees a holding call, so he comes into th restricted area during the down, shoulder bumps the wing official while saying "You gotta call that, you *&$%%^%^!"
Can you enforce the 15 for sideline interference AND the 15 for the obscenity? (And since I'm in NC... 15 for a mouthy assistant coach?) Or, by rule, do you just have to pick one?
