I don't think there's the slightest chance of it happening (nor, indeed, do I think MacGill will cause us many problems) but I think they could do worse.
I don't think Langer is remotely likely to do much in Test cricket any more - I think he's finally been hit once too often, and it's not like his form in 2005\06 was anything to shout about. Yes, Jaques is undoubtedly a very, very good batsman but he's also far from a proven Test quantity.
I do think we'll expose Hayden and Martyn again, and I think we've a good chance of doing the same to Gilchrist, but as I said a little while ago - it'd be darn foolish to be anything resembling certain of that. I certainly think if Clarke plays he'll do not-much.
So yes, I think Australia could do much worse than
As I say - I'm perfectly well aware it ain't gonna happen, but I think were it to do so, Australia would have a good chance.
Certainly I think they'd be foolish to play less than 5 bowlers. I don't think most Australian batsmen are good enough against our bowlers, but McGrath, Gillespie, Clark, Lee, Warne on a green-seamer could be pretty lethal, too.
