Hahaha yeah, that's exactly what I think whenever I hear the Warriors have won. Does Manu actually have any skill whatsoever? The vast majority of the tries I've seen him score for the Warriors (admittedly, I only ever watch the highlights + news reports, if that) are just him flopping over the line in the corner after an overlap which any semi-decent winger (hell, even just a semi-decent player in any position) can do...
He's good in the air. Which sounds funny because he can't catch - but he always gets to the ball over the top of his opponent. He's also very strong too so he scores a lot of tries when he gets up against his opponent one-on-one that a lot of other players wouldn't. He also acts as another front rower from his own end, coming in-field and taking a lot of hit-ups. That's very under-rated in wingers. He's a bit.. weird but he's very valuable.
I used to be his biggest critic but he's just about the best winger in comp now. He's obviously practiced a lot under the high ball. I reckon having Moon inside him is a good combo as he seems to be able to release Manu into more one on one situations close to the line by holding up the defense's centre a bit.
