Jack Egan, an expert on archived footage of cricket history remarked during his video 'The Cricket Archives. Australian Cricket Films 1905 - 1961';
Old times are good times of course, but it's pretty obvious that the facilities have improved a fair bit since the 1930s. I've got no doubt that the standard of cricket has improved too, as it has in all the sports where results can actually be measured. The is no comparison for instance between fielding then and now. The players now are a lot fitter and they're younger too, and bowling, especially fast bowling is a lot more consistent than it was 50 or 60 years ago. Still it's true as the saying goes, a champion in one era would be champion in another era.
So you are right MULOGHONTO in concluding that modern players are better than their counterparts from before the Second World War. However, this conclusion needs to be heavily qualified. Geoff Armstrong makes an important statement in his book 'The 100 Greatest Cricketers';
Sir Donald Bradman was just one of many experts who argued strongly that Arthur Morris was the best left-handed opener he saw, but veterans who watched Morris in his prime never conceded that he was superior to Warren Bardsley, who went in first for Australia from 1909 to 1926.
It is important because it reminds us that there is chain of experts and eyewitnesses who take us back to the turn of the 20th century, and the conclusion they draw is that the skill of Test match players has remained fairly constant over the various generations. Therefore, when we say modern players are 'better' we are talking about incremental improvements in skill, not quantum leaps.
Ashley Mallet is a respected writer and has seen all the best fast bowlers since the 1950s - from Lindwall to Steyn. Yet for him, Ray Lindwall is the doyen of fast bowlers, and better than Malcolm Marshall;
Ray Lindwall heads my list of the five best fast bowlers I have seen. This artist-cricketer changed his pace with all the subtle artifices any fast bowler of any era has achieved, and he did what all great bowlers must do: broke the rhythm of the batsman. At his peak he had the power to slay by thunder or defeat by guile.

So again, we have an eyewitness who transcends generations, and concludes that the best fast bowling really hasn't improved significantly in about 50 years.
Your opinion MULOGHONTO that great players from around WWII, or even WWI, are significantly weaker than their modern counterparts lacks the backing of experts and historians who know more than you do.
Therefore, it is very likely indeed that a quality batsman like Bardesley, or a quality bowler like Gregory, would cope admirably with the rigors of 21st century cricket. And of course the reverse is true, a modern Test batsman or bowler of inferior quality wouldn't survive the rigors of early 20th century cricket for more than a short while.
