Who's done the most for safety?
Hockey's icing rule can be difficult to describe. (Those who recall Chiefs goalie Denis Lemieux's explanation from "Slap Shot" know what we mean.) But there's no mystery about the potential for injury when two or more players barrel down the ice and collide with each other and the boards in pursuit of the puck. Last season, Carolina's Joni Pitkanen broke his heel in eight places on such a play. Now that the NHL and its players have agreed to a hybrid version of the icing rule in hopes of preventing such injuries, which sport needs to make a rule or equipment change to keep its athletes safe?
