DPK i was also all for Adam Ashley-Cooper for being the wallabies 13. He has all the attributes of a strong runner and hard worker, much like mortlock. But recently (after readin many posts in these forums) I've come to realise the importance of the number 13 being able to set-up your outside man. AAC (Adam Ashley-Cooper) while our most consistant wallabies performer last year (with his strong runs/defence) didnt pass the ball that often, and i doubt his offloading capabilities. However his sheer yards he gains over the advantage line surely does outweigh this negative. So i would still stick him at my aussie 13 anyday.
However after watching Will Chambers and his potential (hornes too), his offloading skills were superb, and he is also a big strong runner with good defence. He has more potential at OC as in time he could be able to do all the things AAC (Adam Ashley-Cooper) can do (run hard/straight/get over the advantage line) as well as a few extra (offload, pass, kick, set up his outside men). and with a good year away untill the RWC, i do believe he could just have enough time to make the jersey his own.
If this was a RWC year AAC (Adam Ashley-Cooper) would be the best 13 option, But Im all for shifting chambers in their (off the bench to begin with first) and start developing him asap.
Ps. Didnt mention diggers. I think digby is a winger cos he also doesnt set up his outside man as much, and also runs every what direction to get past his man (which he does bloody well). But this prob makes it worse for his outside man. The only reason for sticking him at 13 would be so he can get his hands on the ball more, cos lets face it every time he does he fucking ripps it up. But from a technical point of view it probably would be wiser to have a straight runner at 13.
