I love it too, and really enjoyed NBC's coverage of the US Nationals.
I believe that in order to send 3 skaters in any discipline to the Olympic Games that 2 members in that discipline must place in the top 10 at the World Championships the year before. I also believe that the host country gets 3 skaters regardless of how they placed at Worlds.
As to Jeremy Abbott being a goofball, I would also like to know how so?
I used to attend a figure skating camp in Aspen CO where Jeremy is from. I shared ice time with him when he was just 10-13. Even then he was an amazing skater, training hard in both singles and dance. He would travel to Colorado Springs each week for lessons and ice time with his dance partner. Even then, there was something special and very dedicated about him. Now that being said, he was a 10 year old boy and VERY silly...but when it came to his skating he was very focused and dedicated.
