Some people are forgetting how demanding it is to play fullback, especially positionally, if you are customarily a winger. Robbo made a few mistakes against a team putting us under pressure. Hicks did similarly when replacing BS earlier on.
Robbo saved tries with good defence, took a couple of pressure bombs, he fielded kicks well and came into the line well. At one point he got out of the in goal in impressive fashion.
He missed one kick badly that led to a try and was slow to get to another. Hardly the poor game as expressed by some.
