Stats are fun, but they also carry meaning. I've always said that there is no single criteria for judging how good a player is, but an accumulation of many relevant points that will decide the better player.
So, if by any statistical measure, the same All-Rounders keep popping up at the top, it surely must say something. Going by memory, the names Sobers, Imran, Botham, Miller and Faulkner feature at the top most often in different statistical analyses.
Having said that, the intangibles also do count as ' points ' that could be used to assess a players performance, the only question being the weighting given to all.
