What are you talking about, of course it's a standard system. Backrow forwards dropping deep is standard, the fact Robshaw and BV did it is irrelevent, they were fullfilling the core Backrow resonsibilites - help out your back three in defence.
Goodes positioning is very poor on that try. He's too flat and too far over subsequently allowing it to bounce and get outjumped by the man coming forward. Which considering positioning is meant to be one of his major strengths..... well.
