Sword of Justice
Arch Winning (36)
Match stats suggest that we won all 10 of our lineout throws against Scotland in the quarter final (Mumm was only on the field for 15 minutes).
Against Argentina we won 12 of our 13 throws and Mumm played 13 minutes.
Are you sure you just don't like Mumm rather than actually having any particular evidence that he played poorly for the Wallabies last year?
Perhaps I have my matches mixed up but I distinctly remember losing 3 line outs in a row in a match when Mumm replaced Simmons. And then the same thing happening the week later.
I think he's a good player but was just not ready in time.
