It is very shameful to send a player back home during the tour. Instead of talking him and giving hime the encouragement and boosting his moral, you are discouraging him for life long.
Coach can talk to him and give him tips on balling as well as encourage him and make his mind set, because in today's circumstances cricket is mind game.
Make up their mind and concentrate on the game.
By this way we are loosing good players day by day.
