The Us can expect at least 1 medal from Women's skating, probably 2-3 or more from short track speed skating, a couple more from regular speedskating, Hockey (men & Women), possible a couple more from Alpine skiing, a couple from freestyle skiing, skeleton and even the possibility of a bobsled medal.
20 medals is quite probable, 25 is realistic, and 30 is not out of the question. By far the most successful Winter Olympics ever for the US.
