AMBROSE'S Period
Amid Ambrose's period, pace bowlers averaged 29.79 runs for every wicket while Ambrose averaged a brilliant 20.99. So Ambrose was 42% superior to the normal bowler in this parameter. The pace bowlers in his time had a strike rate of 63.2 balls for every wicket while Ambrose was 54.5. This relates to Ambrose being 16% better in this parameter. In Ambrose time, pace bowlers had an economy rate of 2.85 while Ambrose's economy rate was 2.30, that is 24% superior to his partners. Considering these three principle playing factual parameters, by and large, Ambrose was 27% superior to the normal bowlers of his period. In measurements, particularly for a similar investigation like this, anything more than 20% is exceptional.
STEYN'S Time
Amid Steyn's time, bowlers average 33.24 runs for each wicket while Steyn averages an astonishing 22.3. Steyn is 47% superior to the normal bowler in this parameter. In Steyn's period, pace bowlers have a strike rate of 61.5 balls for each wicket while Steyn is 41.4. This compares to Steyn being approximately 47% better in this parameter. In Steyn's time, economy rates of pace bowlers are 3.24 while Steyn's economy rate is 3.22. Consequently Steyn is no superior to the pace bowlers of his period in this parameter, which relates to approximately 0% better. So all things considered, Steyn has been 31% superior to the normal bowlers of his era. Keep in mind Ambrose was just 27% superior to his companions.
Time Components
Each era has its concrete factors that distinguish it from another era. Many will accede objectively though that Ambrose’s era was more bowler-friendly than Steyn’s era, many circumstances are heavily in favour of the batsmen now in Steyn’s era. The rule changes, field size, the number of bouncers that can be bowled per over, flatter pitches and technological advancements in the batsman’s bat, etc have all put bowlers in Steyn’s era at a disadvantage. However, how would each bowler do in the other’s era?
AMBROSE IN STEYN'S Time
Ambrose had a career bowling average 20.99, strike rate of 54.5 and an economy rate of 2.30 in his time. Theoretically, if Ambrose played in Steyn's period his bowling average would be 23.43, strike rate 53.4 and an economy of 2.63 based on how far ahead Ambrose was from his contemporaries. These numbers are phenomenal yet similar to Steyn's in this time: bowling average of 22.3, strike rate 41.4 and economy of 3.22. Both Ambrose's and the period's attributes are held by this projection.
STEYN IN AMBROSE'S Time
Steyn's vocation playing normal prior said is 22.3, strike rate 41.4 and economy 3.22. Notwithstanding, if Steyn played in Ambrose's period his bowling average would be 20.22, strike rate 42.6 and economy 2.85 in light of how Steyn separated himself from his contemporaries. These numbers are unfathomable yet still similar to Ambrose's in his time: with a bowling average of 20.99, strike rate 54.5 and economy rate 2.30. At the end of the day Steyn's and the period's qualities are held by this projection.
The Better Wicket Taker
I would like to quote [MENTION=141390]Ellipsism[/MENTION] for this, as I believe he has summed it up perfectly:
"In the end, bowlers are employed to take wickets and no other format is this more important than in Test cricket. “Wickets win matches” the old proverb says.
Ambrose took 405 wickets in 98 matches that is over 4 wickets per match while Steyn has taken 417 wickets in his 85 matches that is nearly 5 wickets per match, despite playing in an era that heavily favours the batsman
CONCLUSION
So the intra-period investigation is demonstrating that Steyn has separated himself from his associates at a more noteworthy rate than Ambrose, 31% instead of 27%. The between time investigation is demonstrating that Steyn would have better numbers in Ambrose's time instead of Ambrose in Steyn's period. In conclusion, Steyn is undoubtedly the better bowler.
