A national team player must be able to play according to the situation. And at every situation, a good batsman must be able to judge the deliveries. If a player is able to do that, he will play. If not, he has to go. This is the professional world of cricket.
I don't understand what JS's point here. Playing for losing will never work for improvement. And I think, those improvement phase for bangladesh should be over by now. We should be able to play for wins; otherwise we should ask ICC to give us a rest.
