If they want the players to be un-emotive robots on field, I kind of wish the players and coaches would start acting that way off-field too during interviews just to hammer home the point of what they're asking for being ridiculous.I have a theory that the underlying motive behind the dissent rule is that it's an attempt to hide the poor standard of umpiring.
By getting the players to stand there and show absolutely no emotion over a free kick gives the impression that there's nothing wrong with the free kick and doesn't visibly highlight the terrible ones.
I'll give it a year or two and the broadcasters will be encouraged by the AFL to not highlight questionable free kicks.
The sad thing is that the AFL appear to think that silencing everyone about poor umpiring is easier than actually fixing the problem.
They already silence the coaches and players be fining them if they publicly question it. How many times are coaches asked about the umpiring during pressers and make a "I can't comment on that" retort?
