Ali Williams has really stepped his perfomance. He was everywhere, acting like a fourth flanker....and also slowly regaining form is his locking partner Jack. McCaw is McCaw, same intensity week in week out.
Francois Steyn was impressive when he came on, set the Boks backline on fire after a dour first half.
Ledesna and Pichot were great for the Pumas. A mention needs to go to Sthephen jones and Alfie for changing the match v Canada. It's difficult to comment on many of the All Blacks and Aussies when the team was so collectively dominant.
4 players not mentioned yet from round 1- Fernandez-Lobbe was absolutely phenomenal IMO for the Argies at 7, Jerry Collins showing some classy touch with both his passing and his kicking(!), Bryan Habana running rings around the Manu, and of course young Losper of Namibia for making the tackle of the tournament, to date, on Hickie.
Jerry Collins is looking great and bringing out never seen before moves (for him at least). In fact he may get kicked out of the hard man's club for daring to put in deft kicks and sidestepping. Chabal's turn of pace against Namibia came as a surprise. Latu, T-Pole (despite his idiotic elbow) and Maka all played suberbly for Tonga against Samoa. (you can probably detect a positional bias here!). Cral Hayman is the best prop/lock/centere in the world!
