- “Players will not adopt helmets by individual choice for several reasons.
- Chicago star Bobby Hull cites the simplest factor: “Vanity.” But many players honestly believe that helmets will cut their efficiency and put them at a disadvantage, and others fear the ridicule of opponents.
- The use of helmets will spread only through fear caused by injuries like Green’s — or through a rule making them mandatory.
- … One player summed up the feelings of many: “It’s foolish not to wear a helmet.
- But I don’t — because the other guys don’t.
- I know that’s silly, but most of the players feel the same way.
- If the league made us do it, though, we’d all wear them and nobody would mind.”
The most telling part of the Newsweek story is in the declaration attributed to Don Awrey. & dquo; When I saw the way Teddy looked, it was an awful feeling... I’m going to start wearing a helmet now, and I don’t care what anybody says.&dquo; Viewers of Channel 38 (Boston) know that Awrey does not wear a helmet.
An “externality” is present when you care about my choice or my choice affects yours. You may not care, but need to know - whether to pass on left or right when we meet. You may not need to know, but care - you will drive whether or not I drive, but prefer that I keep off the road. You may both care and need to now.
