Sure it may get your team ahead, and open an oppurtunity to score and take the match, but can you honestly tell me that you would be 100% happy if the Eels won a Grand Final game on the back of one of these antics?
That's not sport.
Well, as a fan, I dont condone it and wish it wouldnt happen. But if I was a halfback, just got through defending 3 sets on my own line and then one of my team mates took a dive, got us a penalty which gives my forwards a rest and the chance to put some points on, I wouldnt give a damn what the penalty is for or how we got it, id just be glad we got it.
Stealing penalties happens all the time whether it be running at an offside player, holding a defender on you or more recently letting go of the ball when being tackled knowing that the Video Ref will check it for a strip.
in response to your question, would I feel good if Parra won a comp with one of those antics? no, not in a million years.
P.S Thank you for being civilised and actually consider that I might have something relevant to say unlike other people on here who got their panties in a bunch.
