There's no guarantee that Jeremy and Adam (who was also expected to go to Worlds) would have kept the third spot either. They barely did it in 2010 (5th and 6th, respectively) and there were chatter leading up to Nationals that the pair could easily lost the third spot based on how the other skaters were doing.
As I said in past posts on the topic, I feel Jeremy did not show much of a case, even with two medals in the GP, of being sent over the other Nationals medalists. He left a TON of points on the table in his LP. You can tell the judges wanted to send Jeremy -- they gave him the highest PCS by several points. 67 TES (and that score was with Nationals inflation) does not cut it. For perspective, if he turned in that same performance at Worlds with the same score, he would have ranked bottom half of the LP.
Anyway, now that I said my piece, I'm hoping Jeremy will have a comeback and show what he's truly capable of.
