Full credit to Sehwag for not going to public like Ganguly did in the Zimbawe.
We can't criticize Wright since the role of the coach is like the teacher in the school. If the players keep on making same mistake(We all know Sehwag has the habit of throwing wicket away. Commentators often justifies him saying that it is his natural way of playing) it is Coach's duty to rectify it.
