Here are some stats. Eventually I'll post all US results with how they rank all-time.
Junior boys - Tim Smith's 5th place is the best ever placing, beating Andrew Benford's 12th place from 2006. Levi Grandt's 13th place is the 3rd best and Jon Steven's 31st place is the 7th best.
The team 4th place is the best ever, topping the 8th place finish in 2006.
Junior girls - Alex Dunne's (in picture above) bronze medal is the first ever individual medal for a junior girl, this tops Anna Lieb's 4th place finish in 2007.
Men - Rickey Gates 12th = 10th best, Joe Gray's 16th = 14th best, Eric Blake's 23rd = 20th best, Simon Gutierrez 25th = tie for 24th best. Matt Byrne 34th is the best ever 5th man for a US team and Zach Freudenberg 36th = best ever finish for a 6th man.
US 5th and 6th man beat every other countries 5th and 6th man. So I'd say they were the deepest team in the field.
Team bronze medal tops the 5th place finish in 2006.
Women - Brandy Erholtz 11th place ties for the 7th best ever individual performance.
