After Kim Hughes made one of the gutsiest 100's ever made.The huge amount of draws in the 70s and 80s suggests those pitches weren't minefields.
Bat faces haven't changed.
Today's attacking mindset is more likely to lead to dismissals than the defence first attitude of the 70s and 80s.
The big disadvantage for today's bowlers is the thicker bats and short boundaries mean top edges are more likely to fly for six, but on the other side of the coin bigger boundaries meant the ground in earlier times was harder to defend against 1s, 2s or 3s. Let's also not forget how much better fielders are now.
I love Cummins, but let's not get carried away. He's bowling beautifully for his era, just like Lillee did.
Lillie's bowling of Viv at the end of the day at the MCG, in 1981 I think, to have the Windies 4/10 closed out the best day of test cricket I've seen.
