all pretty true, but i don't think its a big prob in afl and no worse than its always been
theres really two types
A] exaggeration or demonstrative. player enhances the offence he thinks is there to make umpire notice
B] complete fabrication, just a straight out con.
not much you can/should do about A]
umpires should maybe get more involved with B]. maybe a warning or a free against. for worst examples the mrp could look at and probably fine for first offence
I'm not very happy though at having a specific rule as I don't think it is that big a problem. as i said before the general 'disrepute' rule could always be used for really bad examples. the game is getting sanitised enough
