I think the bit about the bigger bats, reverse swing as well as spin in ODIs etc. are all good points. At the same time, I also think we tend to romanticize the stuff we watched as kids when it comes to sports. I enjoy the fact that you can bowl proper bouncers in ODIs now, instead of the no-ball when it bounces over the shoulder crap in the 90s. The two catchers compulsory and the whole 15-40 overs of ODIs when so very little ever happened are stuff I am happy we dont have to the same extent now.
I still remember that period in the early 90s when Courier, Sampras, Edberg, Becker all seemed to take turns to being #1 and awaiting with bated breath for the Friday(??) newspaper which was the only time I could see the ATP Top 10 for that week.
Also, we take for granted how exceptionally talented batsmen today are against pace, 140 km/hr is not really fast in 2020s.
On the other hand, I've watched batsmen from England and South Africa in the 90s/00s hopping around or getting beaten when the speed gun is just shy of the 140 mark.
Still, I am more emotionally attached to cricket from the past, the current bunch are very bold and talented, nobody from 'Fab 5' had the guts to do what Pant did in Australia, but those were the days...
