In an article carrying this thread's title, Jo-Ann Barnas of the Detroit Free Press quotes Brian Boitano remarking, "I think she could be unbeatable," when speaking of Alissa Czisny, of the Detroit Skating Club.
Her article (available @ freep.com) references that Czisny sought Boitano's advice last week. After he watched her comeback in the free skate, he felt her competitiveness was confirmed.
Boitano remarked that some skaters are not ready to absorb advice from past champions, but that Czisny is a sponge, taking it all in.
Barnas confirms in this piece that Czisny has been signed to perform in 22 of the 23 Champions on Ice tour dates. The tour will commence shortly after the conclusion of the World Championships. Alissa's only absence on the tour will be the Detroit stop. She has a previous committment in Bowling Green, Ohio on that date.
Congrats Alissa and have a great time!
