The problem with common sense is it's not that common. Canberra Raiders coach Ricky Stuart certainly couldn't see any in the final six minutes as the Green Machine looked to mount a comeback against South Sydney Rabbitohs at Canberra Stadium on Thursday night. Not once, but twice the controversial NRL bunker, led by Henry Perenara, disallowed Raiders tries for obstruction. They were chasing the game, trailing 32-20 going into the final 10 minutes of the game - with Souths down a man after Jacob Host was sent to the sin bin for a professional foul. The second one was definitely harsh - Raiders second-rower Corey Harawira-Naera slipped over as the lead runner, but didn't even make contact with the Rabbitohs defender before Jack Wighton burst through the defensive line for what would've given the home side a slim chance of sending the game to extra time with just three minutes remaining.
