People don't like to hear it, but the game really changed in the 70s with a dominant strategy of bowling based around consistent pace and aggression to really put batsmen in physically more difficult situations more often. The overall approach for the vast majority of Test level bowling attacks hasn't really changed much since then.
Just because people have a weird fetish for Lillee and Viv to bangs their brains out doesn't mean Cricket changed in the 1970s. The Decade is so overrated for Cricket it's straight up comical, there are more tangible developments and differences in last 10 years than between 70s and 50s.
Anyway, when Hayden made his 203, India's 4th/5th bowlers were
- Nilesh Kulkari (166)
- Sairaj Bahatule (67)
In 2008 When Hayden made three hundreds against India, their fourth and fifth bowling options were.
- RP Singh (42)
- Saurav Ganguly (52)
in 2003 When Hayden made three hundreds against England, England's fourth and fifth bowlers were
- Ashley Giles (40)
- Craig White (38)
I'm not even gonna mention Sri Lanka.
South Africa's fifth options in 2002 when Hayden made 3 hundreds was
- Lance Kluesener (38)
Hmmm, so test standard. Now looking at Hutton's big serieses
1950 Ashes, fourth and fifth bowlers were
- Ian Johnson (29)
- John Iverson (15) [19 in FC]
1947 ashes last two games
- Colin McCool (26)
- Bruce Dooland (46)
- George Tribe (165) [didn't play much but 20 in FC with 1000+ wkts]
- Ian Johnson (29)
1953 Ashes
- Richie Benaud (27)
- Alan Davidson (20) [Young]
- Douglas Ring (37)
West Indies 1954-55
- Denys Atkinson (35)
- Frank Worrell (38)
- Frank King (39)
Doesn't look like much of a difference.
