Cerulean, that's a lovely feature about the two Brians. It shows their character as well as their achievements. And it demonstrates that the rivalry between Orser and Boitano was one of the great ones in terms of its contributions to skating, because of the technical advances that resulted from it. What's nice is that both Brians remained active in skating as pros in competition and also in innovative programming. Anyone remember the Carmen they did with Katarina Witt? I believe Boitano was Don Jose while Orser was Escamillo. Also, there was a really interesting narrative skate-dance done to Holst's The Planets, starring the Duchesnays and choreographed by Lar Lubovitch. Brian Orser portrayed Mercury, on skates, while most of the other gods were played by dancers. The long arm of coincidence: Venus was played by a ballerina...none other than Sonia Rodriguez, later to become Mrs. Kurt Browning. I located at least part of it on YouTube:
And now Orser is a coach of Olympic caliber! Don't you love it when things turn out well?
I would choose Yagudin/Plushenko rivalry.
The second must be the battle of the Brians.
