I'm not really too big on stats in general but one of the few statistical records I do make a conscious effort to look at when I judge a cricketer is his performance in various countries. In my opinion, it shows his versatility, his ability to adapt to different conditions, and just his overall skill and greatness. In the discussion about the greatest bowler's, Marshall's name kept getting up and one reason which was mentioned frequently was his consistently superb performances against every opposition no matter where he played them. This, for me separates the greatest from the merely great, the Laras and Tendulkars from the Jayawardenes and Sehwags. Only the very best transcend conditions.
So are there any cricketers whom you consider great but have mediocre records in several countries? Sangakkara for me falls into this bracket at the moment, I love the guy but his below average performances in a number of countries makes me unable to rate him as high as someone like Kallis or Tendulkar. Fair or unfair?
