Aussie, you're argument is good and well thought out, but it just isn't completely true. Hayden was blasted touring sides when in Queensland. There was a thread where I listed such innings against West Indies and Pakistan in the 90s. He's also done more than enough when it was tough. Or games Vs. Australia A or other state sides. These sides contained better bowlers than what was in Test standard. If we are talking about simple technique, Hayden's hasn't been disadvantaged enough by having a 'flawed' one because he has made too many runs against great bowlers. Just look at his centuries and the conditions they were in - check if the opposition or a teammate had a century and who was the highest scorer, etc.
Now, the fact of the matter is that to assume bowlers in the past were much better is just misguided. GO LOOK AT THOSE BOWLING ATTACKS. We had GREAT bowlers in the past,
but they were surrounded by mediocre crap. One great bowler and no one else, sometimes a decent 2nd bowler in sight. There was Hadlee, but surrounded by nobodies, there was Thompson but again, no one of real steel to support (there was Lillee, but in Gavaskar's case he never faced both at the same time and in 79 he didn't face either.) The Windies had at times Sobers leading them, suffice to say, not an attack that would get any plaudits today) S.Africa didn't play and New Zealand held him again
...suffice to say, if there is minnow bashing, you see it there.
It's in the 80s where some of the teams like Pakistan and West Indies actually had a bowling 'attack' consisting of more than 1 real bowler. Against the Windies his record is average (actually, below his own average, but considering the opposition...) but against Pakistan he was great. Australia were crap, Sri Lanka were crap, New Zealand owned him, much the same with England and South Africa didn't play. Gavaskar played more than half his matches in the 80s+ and averaged 46...And that's his great record. Very easy to go through careers like this because all these openers have just as many if not more question marks over them.
Oh lord, this tripe again.
