The coverage of every game in this year’s NHL Stanley Cup playoffs begins tomorrow with three games — including the defending Stanley Cup champion Los Angeles Kings at St. Louis on CNBC — and will feature as many as as 105 playoff games and possibly more than 260 hours of programming depending on how long each series last,  the NBC Sports Group said today. It marks the second consecutive year the NBC networks will televise every game, taking fans into June. NBC, NBC Sports Network, CNBC, and NHL Network will pitch in. In addition, more games will be live-streamed than ever before: Besides TV Everywhere, NBC Sports Live Extra — the NBC Sports Group’s product for desktops, mobile devices, and tablets — will stream games that air on NBC, NBC Sports Network, and CNBC, including the Stanley Cup Final for the first time. NBC and NBC Sports Network will share duties for the Stanley Cup Final series, with the broadcast network showing Game 1, Game 4, and Games 5-7 (if necessary), and NBC Sports Network televising Games 2-3.
