What does he do that a 5/8 is supposed to do?
Before this game he has tried overplaying his hand every week and been nowhere near as effective as he could be.
Results? You mean beating shit teams that are horribly out of form? Do you think those results change with him at second row and Moylan in the halves?
What does he do that a 5/8 is supposed to do? How is that even a f**king question? He creates points. He holds the ball out in two hands and puts pressure on the defence. He draws multiple defenders and passes before the line. He wraps around the first receiver into the backline and picks the right pass or runs it. He measures the ball out the back to the wrapping fullback outside. He hits the lead runner. He creates space for outside runners. He gets in behind the line and offloads. And he forces drop outs.
If he was playing wide back row absolutely he wouldn't have been as effective. The stats prove that without doubt. It's the difference between a ball running and ball playing position. He has been more effective at 5/8 than he was when playing there, and he's been more effective than the other two 5/8s we've played this season.
If he played lock and Moylan 5/8 then no he wouldn't be any less effective, because the way both he and Moylan play in attack wouldn't change. We are playing two 5/8s with both playing either side of the ruck, predominantly with Moylan the wide runner and Cartwright playing at the line, and that wouldn't change if he ran out in 13 and Moylan the 6.
He is an attacking threat, with a game weighted towards ball playing rather than hole running or elusive running, hence 5/8 is his best position.
