In all of sports there is no position quite like it. There they are, wearing more than 40 lbs. of equipment, fit more for a futuristic science-fiction war novel than stopping a tiny rubber disc. Their weapon of choice is a long wooden paddle, which they wave in the way of rival shot attempts, not to mention their opponents’ backs and ankles. They contort their bodies into painful positions like circus acrobats, just to keep their team in the game. When anyone else makes a mistake it is up to them to correct it. But when they make a mistake, everyone stops and notices. “Goalies have to have a screw loose in the head,” Delaware’s junior defenseman John Colford said.
