Personally I think it's just a shame that the leg-theory tactics were used - because that series was indeed the one time during Bradman's career where England potentially had a side that might've been a full match without using unorthodox (whether illegitimate or not) tactics. However, as to the point about all the main Australian batsmen making a decent-ish score at some point - well the leg-theory was not bowled non-stop was it?
England of course were the better side throughout that series - if Australia had wanted to respond in kind then they could have done, somewhat uncharacteristically they elected instead to put being able to claim the moral high ground ahead of fighting fire with fire.
As for the hammering in '28/29 (and of course England's victory in '26) that had, did it not, little to do with the series' between 1930 and 1948? Belonged to a different era. England won both '26 and '28/29 fair-and-square for certain. The '32/33 series will, however, always have an asterisk next to it for mine. Certainly one of the most fascinating parts of cricket history, but not I don't think a series that should be taken alongside any others. In so many ways it was unique.
As I've said a good few times, I don't think there's any reason to consider the use of leg-theory fields (forget the consistently short bowling) aught bar unfair. They were outlawed for a reason. The point of the tactic had always been to make scoring difficult, same as the point of spinners bowling long spells outside leg-stump. I don't condone either tactic, and welcome the fact that both are now outlawed.
But as I said at the start of the whole exchange, anyone who complains about the Bodyline escapade from the POV of the short-pitched bowling then champions Thomson\Lillee and indeed anyone else who's engaged in such activities (which numbers one hell of a lot of bowlers with any decent pace) is indeed a hypocrite.
