Deffinately not the best of all time, although most certainly the best of the modern era. I always like to say back in Bradman's time, cricket wasnt their job, they had to work full time (40 hour weeks) and then train after work, also no planes to take them around, which meant weeks to months on boats and time away from family, plus the fact that Bradman didnt play for a couple of years due to the war. Now adays cricket is their full time job, all they have to do is train, analyse their technique spend hours perfecting it and then implementing it, plus they get paid way more. I'm not saying that its easy to train all the time like modern day cricketers do, but its better than working 40 hour weeks then training for hours on end afterwards. Also, back then the fields were bigger and bats were smaller, now, fields are smaller and bats are bigger, doesnt make sense to me, all they need to do now is get a thick edge and it races away for 4 or even 6, not back then, either 1's or 2's.
