Wagner has always talked this way about herself leading up to Nationals. Before 2010 Nationals, she talked about how she had an advantage over the other skaters because she had made the Grand Prix Final. She skated well in both SP (4th) and FS (2nd), but wound up 3rd and missed a trip to the Olympics.
Last season, she was double-footing many of her jumps, which left her 7th in the SP, 5th in the FS and 6th overall at Nationals. At least she seems to have overcome that particular problem.
Ashley didn't exactly have a good SP at 2010 Nationals. She fell on her lutz. That fall is exactly what cost her the trip to the Olympics.
Last year's Nats was very disappointing :s
As a very open Ashley-fan, I'd like to think she's not delusional in thinking she has a decent shot at the title. She's gone head to head with Flatt and Nagasu earlier this season and came out on top. Unfortunately she *has* said similar things pre-Nationals the past couple of seasons, so yeah, we can only hope this will be the year she delivers.
