You guys are getting way too worked up about this. I admit his rant at the end of the interview was a bit ridiculous, but the bottom line is he set a realistic goal of winning Nationals and doesn't care if anyone else knows about it. He is not a bad runner and the fact of the matter is about any of the top 5 to 10 runners have a shot depending on how the race unfolds. Sigl has not won it yet although he has a strong case that he might.
I cannot wait to see how this race turns out. Regardless of if he wins or loses or does horrible, this is going to be a fun board to read.
