From an American perspective the growth of Clair Egan and Joanna Reid were great surprises. Susan Dunklee had a very inconsistent season. By finishing 13th in the Nations Cup, they will be able to have 4 in each race, this should help. Now there is some good younger athletes, but I doubt that Dunklee and Egan will still be racing when they get to the IBU World Cup.
On the men's side, the retirement of Lowell Bailey and Tim Burke were always going to cause a massive drop off. They dropped from 13th to 15th in the Nations Cup, but they missed the two athletes who is they shot well, had the ski speed to both be in the top 10. Sean Doherty finished in 25th overall, with Nordgren in 57th. Doherty finished the season with some good results, possibly a sign of his potential and realty getting closer. Jake Brown did ok, Max Durtschi as well. For the team to improve, Doherty needs to become a top 20 athlete, Nordgren top 40, and two more need to develop into legitimate contenders for top 60.
