The Persecuted One
Sorry nothing personal but I cant picture the example you are trying to explain. What I can make out though, all harks back to something I have typed before, (and clearly its not gospel but the theory rings true), that, you rarely get dissent when you make a correct call.
So, problem solved, make the right call and you wont be cautioning this player for dissent !
One mans right call is another mans wrong call!
Being in a credible position is often more important than getting the call right, especially with tight out of play calls. You blow the whistle and players turn to see you 10-15 yds away immediately you convey more confidence because of your proximity.
Your point should have been that you rarely get dissent from the team who the call favours.
Dissent is often about getting inside your head as a referee and chipping away at your confidence, and players will do that regardless of right/wrong decisions. Some more than others!
