Team events at the Summer Games brought drama and high ratings. The IOC is hoping for the same at Sochi. Team luge puts one woman, then one man, then a single-sled team (usually two men) in a back-to-back relay.
What to watch for: This sport has been under intense scrutiny since a luger from Georgia was killed on the opening day of the 2010 Winter Games. For Sochi, uphill sections have been added to the track to slow the speed, but at 90 miles per hour around 14 turns, there's still plenty of danger. "Picking your head up creates drag," says Gordy Sheer, a representative for the U.S. Luge Association. "So you're basically trying to drive a sled at 90 mph without looking."
