"Focusing on the aftermath" is precisely why there are changes for the better in football, hockey, and (catcher blocking) baseball as well. Some plays are just disproportionately more inclined to cause injury by their very nature. A guy aiming for the leg of a player (who usually has their leg planted in the ground) is going to cause injury. We shouldn't have to teach people to jump and dive to avoid being chop blocked. If guys were sliding hard into the base, that's one thing. Kicking your leg 4 feet out with minimal effort to touch the base? What the hell is the point other than some phony notion of "tough play"?
