Boston's Stanley Cup-clinching victory over Vancouver on Wednesday night earned the highest television rating for an NHL game in 37 years. Boston's 4-0 win in Game 7 on NBC earned a 4.8 rating and 8 share. That's the best since a 7.6/27 for Boston-Philadelphia in 1974. It's up 2 percent from last year's deciding Game 6 between Chicago and Philadelphia and up 12 percent from the most recent Game 7 in 2009 between Detroit and Pittsburgh.
