Players can't point to the scoreboard replay otherwise it's dissent. As precious as you get.
I'm OK with it. It is dissent by definition, and it always looks ridiculous. Do they think the ump will change their mind?
I'm a big critic of umpiring, but there are things I wish they would be more consistently hard on, and they would disappear overnight. Throws, if it looks like a throw, pay a throw. I do not give a stuff if the commentators or supporters whinge because he might have got a slightly brushed a finger across the ball. Ump should not be thinking hmmm, looked like a throw, but maybe that might have kind-of been almost a handball. If it looks like a throw, just pay a throw.
Late hits or grabs, player not involved in marking contest arriving late and making contact that in any way impedes play. Just pay a 50, consistently, and it disappears in a fortnight, game flows, rules are applied, everybody wins. It might look a bit tiggy touchwood at times, I don't care, not involved in contest, you cannot in any way shape or form impede player. Thats the rule, and thats how it should be in accordance with the principles of the game. ATM they randomly pay 1 in 10 that should be paid. Just pay it. What is so hard?
