If Ledesma's explicit role has now expanded to line out, breakdown, ruck work, forwards link play, etc, for the Wallabies I am not aware of that
Maybe because Cheika doesn't give a fuck what you think about his coaching setup.
and additionally I believe that Ledesma has not coached these full forwards skills at international level before.
That is irrelevant, if he's good enough. Mario stuck his head inside hundreds of scrums at international level (84 caps, 3 tries, 4 World Cups over a career spanning nearly two decades) across the globe, with a fair chunk of forward work thrown in as well. He has previously been a forwards coach at a couple of French clubs, and before you shout down from your high horse "THAT IS NO SUBSTITUTE FOR INTERNATIONALS!" let me just point out that rugby is a pretty simple game, and the same lessons apply to all levels.
Our breakdown work in TRC* was pretty good, so between our "thin" coaching staff something must be going right.
From memory, we won that tournament, undefeated, did we not? Can someone please confirm?
Others on this thread are trying to be nice and point out facts to you, but so far, all you've come back with is pissing and moaning.
So what the actual fuck is your problem?
Do you hate Cheika because Link was fired?
Do you hate Cheika because he won a title with NSW?
Do you hate Cheika because he doesn't return your calls?
Do you hate the Wallabies?
Do you just hate rugby in general? I'd not be surprised, because you're a Reds fan. I'd fell pretty fucking angry too if I had Woody Graham in charge for another year.
Or, perhaps, you going to be one of those people who come back with "I TOLD YOU SO!" even if we lose on the last ruck in the last minute of the final, having pushed the All Blacks into extra time in the greatest game in history?
Probably. Why don't you and wamberal go make yourself some shit sandwiches and reminisce about better times.
