It's actually for the money they did it.
Aamir Sohail had a bit of sympathy for Amir. He said Amir is just a kid and he came into a bad enviroment. If he is in a bad environment he tend to go along with the rest of the group. In that way he is right: if the senior players show the bad example and he refuses to go along he could have felt out of the team.
And it has to be said, that except for these no balls, Amir bowled great. Not great feelings for the rest of the senior players. They should have known better to not get mixed up with this.
Somebody knows whether the ODI series (Twenty20's included) will go on? At the moment I see no sign that it will be cancelled.
