08:21 AM ET 06.01 | Though they play in arenas separated by about 10 miles, the Devils and Rangers certainly offer different drawing power. NBC's New Jersey Devils-Los Angeles Kings Stanley Cup Final opener Wednesday night drew a 2.4 overnight rating -- down 25% from last year's Boston Bruins-Vancouver Canucks opener. That's surprising. Overtime action -- the Kings won at 8:13 of OT -- tends to help an event's TV rating in any sport because ratings tend to peak at the conclusion of events, and overtime extends that peak. And the game pitted teams from the USA's two biggest TV markets. ... the market with the highest local TV rating was hockey-friendly Buffalo, where the game drew 7.8% of local households.
