The greats would have been great in any era. Times and conditions have changed which make comparison hard, but a batsman that scored runs in the past on uncovered pitches would also have got them today. Bowlers that benefited from those conditions would have changed their games to suit – eg: I’m not old enough to have seen Underwood but my dad and uncle both did and are convinced with his accuracy and control, if he bowled in today’s game he’d bowl a different line and get more drs’ed lbw’s than he did back in the day. Tendulkar may have benefitted from 3lb bats and fast outfields but watch the way his feet and hands moved – with that talent he might have played differently in the 50’s, but he’d still have been world class. Warne is simply the best of all time and would have been in any era.
Here’s the controversial one. I’m not sure about the Don. Body line was designed to play on his weakness against the short ball, which wasn’t (really) a valid tactic back then. He might well have adapted had he been forced to, and yes he’d have benefited from helmets and armguards and….. But for all that, he never really had to face an attack as fierce as the windies of the 80’s, Lillee and Thommo, even Wasim, Waqar, Flintoff, Harmison, Curtley and Courtney, etc. And given the improvements in athleticism / fitness in all sports over the years, i dont doubt that while the quicks, Lindwall, Trueman, etc., would always have been quick, they were the exception, and sustained 90mph bowling from both ends for long periods was not common.
I’d pay well to see it though……
