I would agree that regularly at home games you hear supporters shouting at the referee when there is no chance of us getting a decision our way. I would like to see certain offences clamped down on. Yellow cards are given for kicking the ball away and I would like to see them given to players who rush up to stand in front of the ball to stop a free kick being taken.
There is constant grappling in the penalty area from dead ball situations often with the defender having both arms around the attacker. Start awarding penalties for this and after the initial rush of spot kicks players will realise the consequence of their actions and stop doing it.
I totally agree there is a lack of consistency with throw ins as some referees try to pull the player back to where the throw should be taken but others appear happy for players to gain 10 yards every time.
I would like to see referees deal with players who get in their face and start gobbing off. Rugby has it right, first time gets you a yellow second one you're off.
