I am an YK fan too but really guys, his inclusion in the middle of this series would create havoc in the dressing room. The board doesn't like him, many players apparently don't like him. There will be friction in the team, it will rub off onto the younger players too, and whoever thinks our batting will miraculously improve after his inclusion is heading towards disappointment because off-field mood of the team definitely translates into on-field performance. We'll lose our bowlers' performance too.
I think that if we HAVE to include him, then players should be slowly prepared for it mentally by informing them that he ll play for SA tour with the team. He should be slowly phased into the team. These knee-jerk reactions in this tour would harm more than benefit.
Just thinking from Pakistan cricket's point of view and for its benefits.
