The 20-year-old has been in superb form this season and it's often his play-making skills that are lauded but Hatley believes his commitment in the tackle against the Exiles dispelled a few myths about the youngster.
"George is unbelievably confident for a guy of his age," said Hatley. "He's been fantastic since he came back [from international duty].
"Once or twice his defence has been questioned but I thought his defence was absolutely outstanding.
"He was harrying people and he was getting stuck into our blokes to make sure we kept building the pressure on them even when they had the ball."
