The scheduled days and times for certain events in Sochi are being postponed because of fog – and other events are less compelling for U.S. audiences because its athletes have, with a few exciting exceptions, underperformed. And many of the events scheduled to be replayed in NBC’s prime-time coverage tonight are outdoors, so be prepared for the unexpected. On the schedule, among other things: women’s bobsled. To watch it packaged, tune in to NBC beginning at 8 p.m. ET; to see it live, go to NBCOlympics.com.
