LAST Tuesday night, David Pocock was suffering from hypothermia and must have wondered what he had done wrong to have his first Test as Wallabies skipper coincide with one of their most embarrassing defeats.
Four nights on, he experienced the highs of the same position, with his exceptional display against Wales showing he is a true leader, someone who inspires those around him and intimidates those in opposition.
The Welsh are now wondering what they have to do to contain Pocock at the breakdown, especially if the Wallabies persist in the dynamic duo approach by bringing on his near twin, Michael Hooper, in the second half to add even more punch.
But it is Pocock's behaviour as a leader in the lead-up to the Test that has convinced Wallabies coach Robbie Deans he made the right choice in making him skipper in the absence of James Horwill.
Pocock refused to let the Scotland loss get to him, and even though he is nowhere near the oldest player in the squad, was prepared to tell the senior players what they had done wrong and where they had to improve. According to those around the team, Pocock didn't worry about reputations, and made sure everyone knew who was boss, and his teammates responded.
''David did a great job as captain this week, because this was a baptism of fire,'' he said.
''In a week which was unusual, he grew a lot. He has grown as a leader just through his experiences at the Western Force this year. You can see he is calmer, he is clearer. He understands the things which are important, and he will now let some of the peripheral stuff wash off him. He will pursue the end in mind. That's the sign of shifting from management to leadership.''
Under such pressure, weaker characters would have collapsed. ''But he didn't. He got stronger.''
And having Hooper hovering will help Pocock.
''Michael will be a great asset for David. You look at all the great players over time. They've had someone pushing them. No one achieves much from a position of comfort,'' Deans said.
Adding to the full package is Pocock's prowess as a player - he is one of rugby's most devastating pilferers at the tackle area.
''At the breakdown, he's a physical freak,'' Deans said. ''He has a low centre of gravity and has such strength … He's nigh impossible to move, and he gets the benefit of that.''
