A few years before Sir Don passed away, there was a documentary made about him which also featured quite a bit of Tendulkar and Lara. There were side by side video comparisons of Don Bradman's batting technique and flow with Tendulkars. He himself stated that in that decade he thinks he would have probably averaged about 60 in test cricket.
Even compared to the 1990s, quality test cricket today like the ongoing Ashes series is different. The cricket nowadays is more mechanical and intense. The fitness and the professionalism of today's players and gameplay is of a completely different level. I feel that 1990s cricket was more human - more raw. There was more room for mistakes and inconsistency from players even from the best teams, that brought in an element of uncertainty, passions and emotions.
