well not doing that has really worked well hasnt it? anyone who understand statistics understands that it is contextual and their use is not quite as black and white as you seem to think. an average of 20 odd for a middle order bat after 21 innings isnt an utter failure? is it a success in your book? he may come good, certainly, but until he does - in domestic - why on earth would you be happy in losing test after test based on your armchair wet finger in the air guess of who has "talent"?
