Across the 3 matches, other than Smith getting that intercept, what did he do, that Noah didn't do?
I don't think either of them overplayed their hands and both of them leant heavily on the bloke next to them i.e. Kerevi and Farrell. Nothing wrong with that considering both are so young and for Noah, in-experienced. Noah played exactly how you'd imagine a 10 cap Wallaby to if you ask me.
Only thing I wanted more from him is, to be directing Marika and Samu to come back against traffic and target Smith's inside shoulder which we saw time and time again, his weakest point.
You're right in the sense that Marcus Smith didn't have the strongest series (especially in the first two games) and as a result was derided by the English press especially for his lack of combination with Farrell and general defence.
However there was a key difference between the Lolesio and Smith: the actual ability for Smith to read the defense and pass the ball to a player in space - i.e. the ability to ball play. Off the top my head I can think of at least two line breaks effected directly from a Smith pass but not one instance from Noah.
It's commendable that people on this forum are supporting Noah and I can appreciate that he is a young player who needs time to further develop, but this was hardly an introduction to test football. The bloke has played a full series against the French and multiple games against the All Blacks, and over this period of time there's been little development or evidence of any real passing game/ vision, although his goal- kicking has improved.
He's clearly not overplaying his hand and generally defers to the 9 and 12 at both Super and Test level (White and Kerevi/ Simone) to do much of the play- making but I think it made the Wallaby attack quite predictable, relying on the physicality of Kerevi, Valetini or Koribete for anything to really happen.
