Mark, as an Englishman you pretty much know what happens when someone's trying to flop/dive in football. As soon as he gets busted he earns a yellow card. Every single time he gets "yellowed" his club has to pay a fine to the league. Two yellow cards in a game and your fella gets ejected with a red card in his pocket and the club has to pay even more $$$ to the league. Two yellow cards in two consecutive games and our flopper sits out the next game. Five yellow cards in a season and your man ain't gonna suit up the very next time your team plays. I guess a T for each flop would do the trick.
The trouble is that they rarely get booked or sent of for diving as the refs often fall for the act.
Yes, a technical for every flop would be better than my earlier suggestion.
