Maybe so, but I remembered a
cricinfo article:
Loads of things are a both/and proposition. For example, no-one disputed that Australia batted crummily regardless of the pitch (though the last 8 wickets were taken on a drying pitch after rain).
As for the other bowlers, the opinions of the article (including cricket's Mr Opinion of the 50s):
Not all spin bowlers are equal, as we've seen in India and Sri Lanka whether or not they were doctoring their pitches (Certainly, S.Africa couldn't have had too many complains the last time they toured). Johnson only took five wickets in a
match 4 times in 45 tests, and Benaud was playing in his 22nd test at that point and had taken five in a match only twice: in his next 41 tests he would do so 22 times (I think he spent a long part of his early career 'finding' his bowling, being somewhat more preferred for batting). So Laker was the only one to exploit the conditions and to amazing effect, but that doesn't mean other aspects are beyond consideration.
Johnson was also known for his diplomacy, part of the reason he was chosen as captain of Australia. In a Jack Fingleton book, he unintentionally comes off as kind of an idiot with regards to the chucking controversy (although he anticipated the 'everyone does it' brigade by about forty years) but his approach fitted in with his character.
Unfortunately, this is the only copy I could find of the picture of the pitch being swept before Australia's 1st innings:
However, Pathe have footage that although showing none of the wickets, does show part of Australia's 2nd inns in a resolution high enough to actually see the ball (although their cameraman could have done with a few tips on appropriate use of the zoom):
This being Pathe, they only show two of the ten wickets in their finished newsreel.
