The thread title remind me of Dorothy Hamill being called
the last single skater to win the Olympics without a triple jump.
She won 1976 Olympics and Worlds.
She had 2A and that was enough(jumps-wise) to win.
Skaters of next generation like Linda Fratianne, Anett Potzsch and Dagmar Lurz
had triple jumps.
They pushed boundary to end 2 decades of 2A era.
"Is boundary moving now?"
Are Trusova, Shcherbakova and Kihira present day of them?
Pushing boundary to end 3 decades of 3Lz era.
Or skaters like Zagitova, Kostornaia or Sakamoto can anchor current boundary ?
(like Yamaguchi and Kim did.)
BTW,
Wasn't transitional period 1977-(around)90 between 2 era exciting?
As Witt did 1984 and 1988, 3T and 3S was enough to win.
But skaters had different arsenal like we are seeing men comptition now.
