One flag, two penalties

[Doc-WI]

I'm assuming that since you were talking to B's captain that you had already given your preliminary signal for only one foul-holding. If that's the case, then drop another flag at the spot of the pass. Don't be shy about it, be confident and deliberate. Then go and redo your preliminary signal for holding and intentional grounding. Then talk to B's captain, 99.9% of the time the best foul to take is the IG. Make this clear to him, and never set up a player for failure. Enforce the IG, then do your final signals. Personally I like to talk it though even if I'm not wearing a mic, "Holding-offense-that penalty is declined. IG-offense-5yds from the spot of the foul-loss of down-(X)down."
