Brown, now 5-5, said he had grown 4 inches since the 2010 nationals.
But Lysacek's barely noticed 11th-place free skate at his first senior nationals was a far cry from the dazzling effort Sunday that earned Brown seventh in the free skate and rousing acclaim from the Greensboro Coliseum crowd.
"It was a dream come true to get the audience to stand,'' Brown said.
With his long hair tied in a ponytail that bounced off his neck as he flew around the rink, Brown had huge jumps, striking speed on his speeds and leg extension worthy of a ballet leading man.
With the problems caused by his growth, Brown and Ade, his coach of 11 years, decided to put off trying the triple axel for another season.
"In his first year as a senior, it was more important to show everyone he could skate,'' Ade said. "Jason has really proved he is a solid competitor.''
Brown goes on from here to the World Junior Championships, Feb. 28 to March 6 in South Korea. He likely will continue to compete on the Junior Grand Prix circuit for a season or two more.
