Did you ever consider that the reason Donald was so bad in that series was because Hayden's play got to him?
No I didn't, because I know beyond all question that that is not the case. Donald had been a merely good bowler for the last year or two before that series and, like some do, had simply been reduced from good to poor within the space of a little while by the time that 2001/02 season rolled around. Never again did he look all that good, under any circumstances. Donald's bowling that series had nothing whatsoever to do with Hayden and absolutely everything to do with Donald.
The problem with all of your analysis is not that you are necessarily wrong from a statistical point of view, but you completely and utterly ignore the psychology of the game, which at the top level is almost as important as pure ability.
It's extremely important at all levels, and thus I never ignore it. Quite how "statistics" and "psychology" are mutual-exclusives either I don't know, they're two wholly unrelated terms.
We saw Hayden butcher Donald and Pollock on numerous occasions, saw him excell against Shaoib Akhtar and saw him absolutely murder every single team during the 00s.
We did so how exactly? Every time Hayden came-up against a Shoaib Akhtar who could actually bowl (ie not in the 50deg-C heat of Sharjah where no seamer could get through more than a few overs at a time) Shoaib had the wood on him. Pollock had the wood on Hayden whenever he came-up against him on a seaming deck (yes Hayden got the better of Pollock on flatties because Pollock didn't offer much threat on such pitches). And as I've already said that Hayden, or anyone, did well against the Donald of 2001/02 is completely irrelevant - it's no different to doing well against Ajit Agarkar or Mohammad Sami.
Psychologically Hayden had to find his feet. And you were right in that the 125 can't be used to prove anything as he was dropped a number of times during it. Which is why he never really gained confidence until the India tour. After that tour his whole mentality changed. He always had the tallent. You cannot casually stroll up the pitch and smack 140+ kph bowlers back over their heads repeatedly if you don't have the raw talent necessary to handle fast bowling.
I've never said he didn't have the talent to handle
fast bowling, I've said he didn't have the talent to handle fast
swing and seam bowling. If the ball didn't move, Hayden was dynamite against bowlers 130-150kph; if it did, he wasn't much crack at all. That was proven immediately after the India 2000/01 tour (all that tour proved was how good he was against spin when there was no seam around), and it was even proven again in 2004/05, 2005 and 2006/07.
