A major officiating gaffe occurred in the Stanley Cup playoffs when San Jose’s Karlsson scored a goal set up by a hand pass. While hockey officials have the toughest job _ they must be able to skate like the players _ they do not get a pass for their mistakes, either. (AP Photo/Jeff Roberson, File)
