Bradman is being marked down for playing against minnows and bettering his average and
Sobers isn't? Similarly Imran and Murali are marked down for having better home averages than away averages. Sobers isn't. If that is not double standards then what is?
Yes Bradman is marked down for playing againts minnows, but also partially for the rules or the day and other factors. Ask yourself if Imran couldn't get lbw decisions once the ball pitched out side of the off stump how effective he would have been.
With Murali, being marked down for the disparity between his home and away averages is only to diffreciate him from Warnr as they are practically even. For Imran, it was one of several reasons why I don't see see him as the best ever player, including reaching his batting and bowling peaks at opposite ends of his career and never excelling at both at the same time and the fact that he was a poor fielder among others.
As for Keith Miller, all I am saying is that I would rather have a 5th bowler with an average of 34 that a number 5 batsman with a batting average of 35. Whats wrong with that. Sobers legacy is not based on his bowling, he was a more than useful 5th bowler and the best in history at that role, who was over bowled and misused as a strike bowler and alternately as a stock bowler who bowled two types of spin and also seam who wal one of the greatest fielders ever and lights iout in the slip cordon. Oh, and by my ratings the thirs best batsman ever.
Regarding Bradman again, for instance, Everton Weekes averaged over 100 vs India, but we don't rate him based on that. We rate him based on what he did vas Lindwall and Miller and Trueman ect and Bradman out side of Larwood at his best for one season, never faced an attack like Lindwall and Miller, not a double standard, it's one we use for everyone.
