Grace physically beating a young player for using nets he didnt think were ready
That was kept hidden from the public for ages. Kudos must go to the historian who uncovered it.
WG was a master at cover-ups. Certainly, if this cricketing Goliath told you to keep mum, you unquestioningly did so. The disappearance of his cousin, caught thieving in a dressing-room and sent off to the States, sits unexplained in every contemporary publication. It serves to illustrate just how powerful and influential Grace was.
Armstrong timewasting and making Woolley wait 18 mins from the time he got to the crease to the time he faced his first ever ball in Test cricket in order to make him more nervous.
That was diabolical. Several of these "trial balls" rolled out all the way to the boundary, unimpeded by the languid Aussie fielders.
'Walking' is considered by some a post-war ideal that grew. Players previously seldom walked.
Lord Harris was one who always held his ground and left the decision in the hands of the umpire.
In 1896, Lohmann and other professional 'rebels' refused to play Tests unless their wages increased
Quite rightly so, in light of the shamateurism of such money-grabbing fiends as WG, but how does this fulfill the OP's criteria?
The great 'throwing' incidents of the late 1890s/early 1900s where a 'chucker' was seen lurking behind every tree and politics and arguments were common place.
Harris always felt that the major reason for the chucking problem of the early 1880s was the irresolute stance of the on-field adjudicators. "When are you umpires going to do something about this?" he demanded of Bob Thoms.
"My Lord," came the icy reply, "we are going to do nothing. It is you gentlemen who have got to do it."
In the 1884 Roses match at Old Trafford, Ted Peate watched in outrage as George Wootton allowed Crossland (a "pure throw", apparently) to launch his crooked monstrosities without question. When the Yorkshire spinner himself bowled later in the match, he went up to Wootton and dared him to take action when
he chucked it. Needless to say, the timid official did nothing, so Peate rounded on him disgust: "There! That shows what you oompires are orl worth!"
The 1950s were closest but even then there were issues.
Lockie's chucking England to the 1953 Ashes, along with the controversy-laden 1954 MCC visit to the islands, spring to mind.
