You lose the benefit of the doubt if you don't offer a shot. He was lucky not to be given LBW, it was worth a big shout.
As far as the C&B goes, that's cricket. When you are out of form things seem to go against you. If he was in form he would have got that out of the middle of the bat, instead of missing it by 3 inches. Maybe the reflexes are just slowing up a little too much for the big man, might be time to move on. We've got a pretty seasoned campaigner in Katich there at the top now, so why not get Jacques back and get him some more test experience before the Ashes.
