Unless they change the laws pococks biggest strength is going to be is downfall... the pure "fetcher" is on the way out... with ALL players trained to turn ball over and the hold the ball for a few more seconds in the tackle, the "fetcher" is now becoming redundent... Look at the world cup squads.. nobody has a backup 7... they are going for bigger stronger players with players who "can" play 7 .. except Aussie, they have noone to cover... unless things change the 7 needs to be a link man, tackler, fetcher, and ball carrier... Pocock is really only good as a fetcher and tackler(ad not a dominant tackler either)... McCaw saw this coming, he has greatly changed his game in the last couple of years, Pocock needs to do this or he wont last very long.
i actually disagree with you there... i think the 'fetcher' will always have a big part to play in the game.
i can see what your saying though... but for mine, i dont think the direction the game has headed has caused McCaw to alter his game to that link role he's playing...
i think the link role he's playing is more of a personal evolution in Richie's game that he's had to make because of 2 things.
1 - His age... he's 31 in September... he's played close to 100 tests and over 100 super games. while hes still in incredible physical shape... he doesn't have the ability to hang in there at the breakdown as long and as often as he did when he first hit the scene. Pocock for mine is the opposite... hes young, strong and fearless so he looks like more of a 'fetcher' because he's more active at the breakdown.
2 - His aura... he's Richie McCaw... he is probably the most influential figure in the game. Teams spend whole training sessions going over how to blunt his affect on a game. he commands HUGE attention anytime he goes near a ruck. so because he's got alot of extra attention on him he's developed into a far 'smarter' player at the breakdown. where Pocock go in all guns blazing and attack every breakdown because he's just a beast... McCaw will weigh up each situation and decide whether its better for him to go into the breakdown or to fan out and play another role... whether that be as another defender aiming to turn the next ball runner over... or as a link man with the ball in hand.
i think Pocock is at a different stage in his career.... he's a savage... an absolute beast. so he can get away with just going in all guns blazing. but as his career goes on... people will start to figure him out... and he will also get older... his game will have to evolve like Richies has.
and thats why Richie McCaw is so damn good... most 'fetchers' are really awesome when they first hit the scene... but as they get older they lose there effectiveness because they cant rely on just attacking every single breakdown. McCaw however has evolved his game so much so that he's still very effective at the breakdown... not as prolific has he used to be... but he makes up for it in his linking game.
so you right in the fact that Pocock will need to learn to change his game.... but i think thats the natural evolution of a fetching openside flanker... not so much because the game has changed so much that fetcher's will no longer be in the game.
