i ent think this "they haven't seen bradman can't devise a plan for him" argument hold any water.... simply because...
so what was bradman watching videos of the bowlers with hawkeye and all that back in dem days before he go out to face them??? NO! he was at the same disadvantage as the bowlers would have been, he would be facing the same unknown quantities... Also, take into account that the condition of the pitches in bradman days was much worse than today, not pampered by groundsmen, rolled to perfection etc...
that said, its also noteworthy that lara has faced the very best of bowling the sport has ever seen... Also, Lara has had to play from the most disadvantaged position of any premier batsmen on the planet... He is always coming in at 5-1, 10-2, 21-2 when the ball is still shiny and new the bowlers still fresh and scenting blood and the pressure on.. The openers before him never gave him any consistent foundation to build upon from Phil Simmons to Stuart Williams, Sherwin Campbell, Philo Wallace, Clayton Lambert, Suruj Ragoonath, Adrian Griffith, Devon Smith, Darren Ganga etc etc etc... All thru the years these openers were a highly inconsistent bunch which cannot be said for what Bradman had to deal with back in his day, or Tendulkar over in India, or Ponting in Australia...
Its an interesting debate that will never have an answer.. Its like comparing Ronaldinho to Pele and Maradona, you just can't come to a conclusion..
