That's far too simplistic. An openside could have an extremely high presence and a ruck and not being doing their job. An example of this would be providing a target for opposition forwards to clear out one pass off the halfback. That would not be an openside doing their job at all. That would be an openside playing far too tight and not utilising their primary advantage over the other 7 forwards, their mobility.
Pocock was a master at picking his rucks, as was George Smith so I'm not sure you would use that as an argument against him.
"Presence at the breakdown" is far too vague too. If a player had the best possible presence at the breakdown, he would like win a few pilfers/penalties and neither make a tackle or a run all game.
Presence was a bad word of choice then. How about effectiveness at the breakdown.
In regards to your comment about slowing down opposition ball, you have to consider the affects of that. The more rucks they have a presence in, without actually effecting anything increases the risk of a penalty and limits the player's chance to get to the next one which may be a better opportunity to pilfer. Hooper does a great job getting in and getting out, not getting in a wrestle with a tight forward without really slowing the ball down which a number of players actually do. It also limits the ability of the player to be free to make cover tackles which given our still porous defence is pretty important right now. Hooper has made countless cover tackles.
Pocock has made countless cover tackles also, including many try-saving tackles. And he actually seems to concede less penalties then Hooper. Pocock was great at slowing the ball down without conceding a penalty. You are implying Pocock isn't mobile - he got around the park very well.
What you also need to consider is Pocock has not played a lot in what has probably been one of the weaker Wallaby teams in recent years. When he last played a full test season it was alongside Palu, Horwill at his best, Vickerman, Sharpe, Elsom, etc. Since these players have left or been injured and below par the team definitely is defending less dominantly than in the past. It's harder to dominate the breakdown when the offence is going forward into the ruck and you need to retreat then come through the gate.
I did not consider this. Good point. Although to be fair Elsom was injury plagued and never performed to level we expected of him, Sharpe flopped all over the ruck, Palu was on and off, Vickerman played only a handful of games in the WC.
However agree it is quite a different wallaby side.
With regards to turnovers and tackling like a machine, Hooper is topping the tackle count almost every game and getting close to 2 pilfers/penalties a game so you cannot say he is not getting the job done in that regard.
Never said he wasn't, However Pocock was the same except I think was a more dominate tackler and more consistent pilfer.
Perhaps Hooper is not the better option. But you cannot just blindly say that Pocock is without a doubt the only option to look at. Also the comments like him being the only player other teams fear is hyperbole. Our disappointment half of the time is a result of us building up these players in our mind on the back of a few great performances (like the RWC QF) as if they do that every single game, and then acting shocked when they don't.
