NBCSN is wall-to-wall today: 24 uninterrupted of coverage, some of it live, from early morning today until the same time tomorrow, at which time the cycle begins again. Highlights will vary according to your interests, but mine includes the live coverage, at 7:10 a.m. ET, of the USA women’s hockey team facing the Olympic athletes from Russia – competing individually, not representing their nation, because of Russia’s official exclusion from this year’s Winter Games. Also, late at night, at 12:30 a.m. ET, NBCSN presents delayed coverage of men’s curling. It’s the U.S team during this year’s host nation, South Korea, and the crowd reaction, no matter what it is, ought to be fascinating. Other delayed curling action is provided today on CNBC, with its only televised event of the day: the gold medal match in mixed doubles curling.
