To the best of my knowledge, not a single professional cricketer (or cricket commentator) has called for bouncers to be banned from the game following the death of Phil Hughes. Inviting the batsman to hook a high ball, at the risk of mis-timing the shot and giving a catch, is an integral part of the game.
Cricket has always had its dangers. (I've been knocked unconscious twice while batting - and that was just playing with my mates in the park when I was a kid!). A few people die every year as a result of playing cricket. (Most of those deaths are among amateur players, and so don't get the worldwide coverage that Phil Hughes' death did). However there are still far fewer deaths and serious injuries than in many other sports, such as rugby, yachting, power-boating, skiing and equestrian sports.
