Leg theory was a form of body line and the whole England bowling section of that squad was named by the press as "body line boys." All sanitised ways of saying "intimidate the batsman." In all, sport but sporting?   

Yes, we can all speak of times past. I recall Mike Gatting doing an impression of a panda for a couple of months after getting one in the face. I bet most of us, me included has had decent bruises. Sport in itself can be dangerous for those involved. At least we choose. Horses being put down after trying Beeches Brook or greyhounds being treated as per the disturbing documentary on the BBC recently.. We at least choose to participate in sport.

This is an unfortunate one off, devastating for those involved and sobering for we cricket fans.
