Skills demo: Loading a defender | Rugby Tonight 

+rmccaw7 Which two? Healey played mostly scrum-half or wing and occasionally flyhalf. O'Driscoll played almost exclusively outside centre. Burrell's played so far probably 90% of his rugby at inside centre. Apart from that, I don't get why it would be unbelievable?

It sounds like he slightly mis-spoke. He’s talking about picking which side of the defender to run at. When he says ‘pick at that shoulder’ I think he’s actually trying to say ‘pick that shoulder’ meaning pick the gap either side of the defender. Hope that helps!
