I don't mean to sound unsupportive here, but did you deal with it on the day? Did they pick up cautions for reckless challenges, dissent, etc? Sometimes it can seem like the easiest thing to let them get away with it, but they will just do it week and week again if that happens, and you won't feel too good after the game.
The reason I ask is this used to drive me round the bend as a RefsSec. I'd get comments in match reports with phrases like "worst behaved team ever", then I'd look further down the form and see there wasn't a single caution in the game. Not saying that was the case here, but it definitely happens.
I'm generally quite laid back when it comes to cards, but on occasions where teams have pressed the button I've responded accordingly. If that means they get 10 cautions then so be it, and I think I still hold the most records in county cup finals with 9 yellows and a red to one team. They didn't want to play, wouldn't listen to reason so I used the only thing available to me, the things in my pocket. I only mention this as, for all it wasn't the most enjoyable of cup finals, I certainly felt better after it than I would have done had I let them get away with it.
