Campbell said the Hockey Ops people showed the [general] managers clips to outline what an illegal or late hit was during their annual meetings last spring. "We just showed them a couple of plays, five or six or seven, where we combined all the criteria," Campbell said.Here's a novel idea: Maybe the NHL could show the same instructional clips to its fans (i.e. its paying customers) and media -- to eliminate the confusion? Or does the league feed off the controversy? Sure looks that way. To nhl.com writer Dan Rosen's credit, he attempts to go into some of the particulars of league policy. Still, video clips, please.
