After disappointing losses, Melbourne and South Sydney each have a point to prove in this heavyweight duel.
The Storm, who were soundly beaten by the Raiders in round three, have conceded they need to tweak their structure to suit the ad-lib nature of the game due to the new six-again rule.
The Rabbitohs, on the other hand, were outclassed by the Roosters - marking consecutive defeats - and need to build momentum.

It's always intriguing when Damien Cook and Cameron Smith, the current and former Australian Test hookers, lock horns. But even more so this time given the new six-again rule and its impact on dummy-half play. One would expect the quick ruck speed to suit the dynamic Cook more than Smith, but the all-time legend has the nous and experience to exploit it too.
