What is this crap about big averages against Zimbabwe? Do you know how many tests Australia has played against Zimbabwe in the last decade? THREE. And against Bangladesh? Two.
Hayden has never dominated a great attack, but how many players do? For some reason, everybody has this idea that every other period in test history has been like the 90s with 4 or 5 all-time great attacks, but it's really not true at all. He has, however, done the business against India in Indian conditions where he scored 500 runs in a three test series, scored a brilliant career-defining century in sweltering heat on a turning pitch against an attack of Waqar/Shoaib/Razzaq/Saqlain/Kaneria, and dominated test cricket the world over in a purple patch that saw him average in the 70s for a period of several years. His average was not "about 75 after the triple century against Zimbabwe", it was about 57 then and has fallen in his slump since. Your short memory with him also doesn't seem to extend as far back as the LAST Ashes series, where he scored three centuries against a a varying bowling attack that included Hoggard, Harmison and Giles at various points, as well as Caddick who is obviously a perfectly decent bowler.
Hayden isn't the best test opener of all time or anything, but you don't average 50+ for 71 tests and 57 odd in a first class career that includes years of batting on green tops without being a good player, and to say that Strauss who is unproven in test cricket and certainly struggles against spin and Trescothick who has been a career-long walking target against bowlers who can move it away from him are "much better" is absolutely ridiculous.
And as far as Gilchrist goes, well that's even worse. Gilchrist has always been an inconsistent batsmen as fits his playing style, but the fact that he's been consistent enough to average in the mid 50s and maintain a strike rate in the 80s is testament to how incredible he has been. Gilchrist is, quite simply, a once in a lifetime cricketer who has single-handedly redefined the position he plays. To suggest this England attack is so good that the guys he has scored against in the past like Donald/Pollock/Ntini and Wasim/Waqar/Shoaib are useless village bowlers that he just bullied is absolutely insane.
Frankly, this whole discussion about the Australian team is going further and further off the planet. This England team is a good team, but they have a hell of a long way to go to even be worthy of comparison to a team that has dominated test cricket for a dozen years. And for all the talk of how Australia have just been a pack of overrated hacks living off weak attacks, it's funny that nobody else in the world has managed to beat every other team and have 3 or 4 batsmen averaging in the 50s, isn't it? I don't suppose it could be that the Australian team has actually been incredibly, amazingly good and they've just been outplayed in one series?
