I didn't say religiously hold position. Sometimes you have no choice. Sideline as an extra defender ? Since the corner post is no longer out, its a poor defender. If someone scores on the inside its the centre and the cover defence @ fault not the winger.If Tui religiously held his wing position and the centre goes through untouched then it's just as much his fault. Even though the props do most of the grunt work, wingers are the most likely to be stuck between a rock and a hard place.
